[Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language.

The type of a geographic name based on its scope of use, quality of source and/or its transliteration status. [Desc] NA The character set used for the display of characters with diacritics and special characters in a geographic name. [Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB).

[Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. NA [Desc] NA A boundary that has been configured to follow a man-made separation that follows neither physical terrain (or geographic) features (for example: peaks, ridges, or drainage) nor generalized geometric configurations (point-to-point line segments, arcs). [Desc] Such boundaries include ethnic separations, historic-, economic-, or military engagement lines, city or cadastral limits, walls, canals, rail lines and other man-made features. A boundary defined by geometrically constructed curve. [Desc] For example, an arc based on a centerpoint and a radius. Often used at sea where natural features are not readily accessible as the basis for boundary specification. A closed boundary connecting and surrounding the islands of an archipelagic State; archipelagic waters are those within the baseline and maritime zones fall outside the baseline. [Desc] (UNCLOS Article 47, Archipelagic baselines, item 1) An archipelagic State may draw straight archipelagic baselines joining the outermost points of the outermost islands and drying reefs of the archipelago provided that within such baselines are included the main islands and an area in which the ratio of the area of the water to the area of the land, including atolls, is between 1 to 1 and 9 to 1. An anthropogeographic boundary that is based on cadastral limits. [Desc] An anthropogeographic boundary follows a man-made separation that follows neither physical terrain features nor generalized geometric configurations. A boundary defined by all or part of the outer limit of a drainage basin, which distinguishes the headstreams that are tributaries to different river systems or basins. [Desc] The drainage limit does not always follow the ridgeline or the highest peaks in a range. A boundary established by alternating peaks and lines of drainage, descending along a drainage line from one peak to the point where it meets a drainage line from another peak, along which it then ascends. [Desc] NA An anthropogeographic boundary that is based on an economic line. [Desc] An anthropogeographic boundary follows a man-made separation that follows neither physical terrain features nor generalized geometric configurations. A boundary that follows a line connecting points having the same elevation value relative to a vertical datum. [Desc] NA An anthropogeographic boundary that is based on ethnic separations. [Desc] An anthropogeographic boundary follows a man-made separation that follows neither physical terrain features nor generalized geometric configurations. A boundary defined by the outer edge of the continental margin (the submerged prolongation of the land mass of a coastal State, consisting of the shelf, the slope and the rise, but does not include the deep ocean floor with its oceanic ridges) or a minimum of 200 nautical miles distant from the territorial baseline. [Desc] (UNCLOS Article 76, Continental shelf, item 7) The coastal State shall delineate the outer limits of its continental shelf, where that shelf extends beyond 200 nautical miles from the baselines from which the breadth of the territorial sea is measured, by straight lines not exceeding 60 nautical miles in length, connecting fixed points, defined by coordinates of latitude and longitude. A boundary defined by the shortest path between two points on the surface of a spheroid (an ellipsoid of revolution). [Desc] NA A boundary defined by the shortest path between two points on the surface of a sphere. [Desc] In the Mercator projection a great circle appears as a straight line. An anthropogeographic boundary that is based on an historic line. [Desc] An anthropogeographic boundary follows a man-made separation that follows neither physical terrain features nor generalized geometric configurations. A boundary that follows the general midline of a lake, defined by straight line segments drawn roughly midway between opposing shorelines. [Desc] NA A boundary that follows the left bank edge of a watercourse. [Desc] The left bank is determined by facing downstream (in the direction of flow) and the bank edge is typically based on average water flow conditions. A boundary that follows the principal navigable channel of a stream. [Desc] NA A boundary defined by straight line segments drawn between opposing shorelines of a waterbody (for example: a stream) that are formed by connecting the midpoints of transects strung between opposing points (for example: significant turns or projections) along the shorelines. [Desc] Because strict equidistant lines can become very complicated, agreeing states often resort to drawing modified or simplified lines which may deviate from or smooth out complex lines by leaving out certain intermediate turning points. A boundary defined by a meridian (a line of constant longitude). [Desc] NA An anthropogeographic boundary that is based on a military engagement line. [Desc] An anthropogeographic boundary follows a man-made separation that follows neither physical terrain features nor generalized geometric configurations. A boundary established by a tangent of the seaward landmass at low tide elevation as depicted on the claimant State's submitted large-scale charts. [Desc] (UNCLOS Article 5, Normal baseline) Except where otherwise provided in this Convention, the normal baseline for measuring the breadth of the territorial sea is the low-water line along the coast as marked on large-scale charts officially recognized by the coastal State. A boundary defined by the outer edge of the continental margin (the submerged prolongation of the land mass of a coastal State, consisting of the shelf, the slope and the rise, but does not include the deep ocean floor with its oceanic ridges) or a maximum of 200 nautical miles distant from the territorial baseline. [Desc] (UNCLOS Article 76, Continental shelf, item 1) The continental shelf of a coastal State comprises the seabed and subsoil of the submarine areas that extend beyond its territorial sea throughout the natural prolongation of its land territory to the outer edge of the continental margin, or to a distance of 200 nautical miles from the baselines from which the breadth of the territorial sea is measured where the outer edge of the continental margin does not extend up to that distance. A boundary defined by a parallel (a line of constant latitude). [Desc] NA An elevated boundary that follows the ridgeline or the highest peaks in a range. [Desc] NA A boundary that follows the right bank edge of a watercourse. [Desc] The right bank is determined by facing downstream (in the direction of flow) and the bank edge is typically based on average water flow conditions. A boundary that follows the edge of a waterbody for which there is no well-specified direction of flow (for example: a lake or ocean). [Desc] In the case of an ocean, the boundary may follow the normal limit of wave action above the higher high water line as defined by the National Authority. A boundary defined by the shortest path between two points. [Desc] As the shape of the earth is curved, 'straight' is dependent on how the curvature is distorted by a map projection. At large scales and short distances 'straight lines' in all map projections are equivalent; at small scales the curvature of the surface of the earth allows for a variety of approximations to 'straight', for example a geodesic line and a great circle line. A boundary comprised of a system of straight lines joining specified or discrete turning points on the low water line that States may employ to simplify definition of a coastline that is either deeply indented or is cut into or fringed by nearby islands. [Desc] (UNCLOS Article 7, Straight baseline) In localities where the coastline is deeply indented and cut into, or if there is a fringe of islands along the coast in its immediate vicinity, the method of straight baselines joining appropriate points may be employed in drawing the baseline from which the breadth of the territorial sea is measured. Where because of the presence of a delta and other natural conditions the coastline is highly unstable, the appropriate points may be selected along the furthest seaward extent of the low-water line and, notwithstanding subsequent regression of the low-water line, the straight baselines shall remain effective until changed by the coastal State in accordance with this Convention. A boundary defined by the shortest path between adjacent points in a series. [Desc] NA A boundary that follows the deepest part of the main channel of a stream. [Desc] On occasion, a thalweg boundary may instead follow the principal navigable channel of a stream. Treaties do not always specify which interpretation of thalweg is intended for a boundary. A boundary extending from the deepest part of the main channel of a stream to the peak of a nearby mountain. [Desc] NA An anthropogeographic boundary that is based on municipal (for example: city) limits. [Desc] An anthropogeographic boundary follows a man-made separation that follows neither physical terrain features nor generalized geometric configurations. No Information [Desc] NA Not Applicable [Desc] NA Other [Desc] NA NA [Desc] NA The boundary is not governed by a formal legal agreement (as opposed to de jure). [Desc] A de facto boundary may, however, be accepted by both authorities without dispute. Under current treaty practice, the boundary has come into force pursuant to a treaty, agreement (including bi- or multi-lateral negotiations, decisions, exchanges of notes, or other legal instruments), or a United Nations Security Council Resolution. [Desc] Most boundary treaties come into force when there is an exchange of instruments of ratification. At the present time a lack of registration with the United Nation (which is required by Article 102 of the UN Charter) has no effect on the instrument being in force (the only penalty being that the unregistered treaty may not be invoked before any UN organ). A de jure boundary is usually demarcated, but it can also remain delimited. Disputes may arise over segments of a de jure boundary, but these segments are generally not labeled as 'in dispute'. Boundaries established between colonial powers or as administrative lines within a colony that become the boundaries of post-colonial States who do not reconfirm their mutual boundary by treaty may be termed 'historical de jure boundaries'. A boundary whereby one or both adjoining authorities contest some portion(s) of or an entire boundary. [Desc] Disputes can be active or dormant and the parties can respond in varying degrees of intensity ranging from hostile belligerence to cooperative conciliation. Among geopolitical entities a boundary dispute is usually a territorial dispute and very often involves contention over the exploitation of natural resources. A boundary that is not in dispute. [Desc] NA No Information [Desc] NA Not Applicable [Desc] NA Other [Desc] NA NA [Desc] NA A boundary having an established, accepted delimitation where no significant sections are in dispute by the adjoining authorities. [Desc] Some definite boundaries may not be governed. Definite geopolitical boundaries are typically recognized by the United Nations. A boundary that is vaguely delimited, so as to question the accurate delineation of territory and its depiction on cartographic products, but that is not actively disputed by the adjoining authorities. [Desc] An indefinite boundary is typically agreed by the two authorities concerned. In the case of geopolitical entities it may not have been registered at the United Nations. Sometimes shown on maps distinct from definite and in dispute boundaries. A boundary whereby one or both adjoining authorities contest some portion(s) of or an entire boundary. [Desc] Disputes can be active or dormant and the parties can respond in varying degrees of intensity ranging from hostile belligerence to cooperative conciliation. Among geopolitical entities a boundary dispute is usually a territorial dispute and very often involves contention over the exploitation of natural resources. Has not been defined by either of the adjoining authorities. [Desc] NA No Information [Desc] NA Not Applicable [Desc] NA Other [Desc] NA NA [Desc] NA A form of military disengagement line established by opposing groups as a result of an armistice (a temporary peace agreement). [Desc] For example, the Armistice Line established in 1949 in the Middle East. A line established where active hostilities have been suspended, but where an armistice line has not yet been agreed. [Desc] NA A limit of an area unilaterally claimed by one State or political entity without consent or negotiation with the adjacent State or political entity. [Desc] NA A line established to regulate matters between nations or groups over a specific area or territory. [Desc] NA A form of military disengagement line established by opposing groups as a result of the cessation of hostilities. [Desc] For example, the Military Demarcation Line established in 1953 between North and South Korea. A boundary separating subordinate administrative divisions (for example: a state, county, township, province, district, territory, and oblast) in a State or other geopolitical entity. [Desc] States are generally divided into first-, second- and lower-order administrative divisions. With only minor exceptions (Egypt-Sudan, Kenya-Sudan), administrative boundaries are contiguous with international boundaries. In rarer instances, administrative boundaries serve in lieu of international boundaries (Ethiopia-Somalia and the former Oman-UAE boundaries). A boundary separating geopolitical entities that is not classified as a more specific geopolitical line type. [Desc] NA A line of demarcation established by colonial powers between their adjacent colonies. [Desc] For example, the line established by treaty in Paris on 10th of February, 1763, that put an end to the American intercolonial wars. By its provisions, France gave to England all her possessions in America 'east of the Mississippi, from its source to the river Iberville, and through Lakes Maurepas and Pontchartrain to the Gulf of Mexico'. Spain, which had also been involved in war with England, ceded East and West Florida to that country in exchange for Havanna, while France gave to Spain Louisiana. The line of separation drawn in Bosnia and Herzegovina separating the ethnic Serb populations from other Bosnians. [Desc] A United Nations patrol zone bounds it on both sides. A line of separation under the specific arrangement concluded in 2000 between Guatemala and Belize. [Desc] Guatemala, which has claims to large portions of Belize and disputes the international boundary, agreed to an alternate line, surveyed separately but tangent with the international boundary, that would permit Belize to extradite squatters residing along the boundary back to Guatemala. A line of separation between military forces that has been agreed by both forces but not necessarily accompanied by a cessation of hostilities. [Desc] For example, between India and Pakistan in Kashmir established as a result of the Simla talks in 1972 that clearly delimited the 1949 Cease Fire Line with minor modifications. A line created when political or military powers cannot quickly or easily agree to an alternate line of separation between contending parties. [Desc] For example, the 38th parallel was created as a line of convenience between communist and democratic forces on the Korean peninsula in 1945. A line of separation to which military forces have withdrawn. [Desc] NA A line of separation recognizing the disengagement of military forces. [Desc] For example, an Armistice Line and a Demarcation Line. A line of separation separating subordinate administrative divisions where two States or other political entities have agreed to a non-prejudicial de facto boundary while pending final de jure settlement. [Desc] For example, between Somalia and Ethiopia. A line of separation that is not a formal international boundary because one or both parties may not accept the line as official. [Desc] Usually established by a specific treaty. An UNCLOS boundary that divides overlapping maritime limits beyond the territorial sea in exclusive economic zones and on continental shelves. [Desc] Under UNCLOS (United Nations Convention On The Law Of The Seas) States have the right to regulate economic activity but cannot restrict freedom of navigation within a claim boundary, which are considered high seas. No Information [Desc] NA Not Applicable [Desc] NA Other [Desc] NA An administratively subordinate division of a geopolitical entity. [Desc] A geopolitical entity (country) is typically divided into first-, second-, and lower-order administrative divisions. First-order administrative divisions are immediately subordinate to the government of the geopolitical entity, with second- and lower-order divisions subordinate to those above them. Examples: (first-order) a United States state, a German Land, a French region; a Canadian province; (second-order) a U.S. county, a French department; (third-order) a U.S. township, a French arrondissement; (lower-levels) a French commune. A 2-dimensional geometric primitive, locally representing a continuous image of a region of a plane. [Desc] Its subtypes include (but are not limited to): GM_PolyhedralSurface (which aggregates GM_Polygon). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the accuracy of the vertical position of a feature, as a category. [Desc] NA The method by which the absolute horizontal accuracy was derived. [Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the horizontal accuracy of the geographic position of a feature, as a category. [Desc] NA A narrative or other textual description that records a general assessment of the quality of a resource (for example: a data instance, a data set or a data processing activity). [Desc] The quality of a data resource is dependent on the data providers knowledge regarding the lineage of the data and the processes that have been used to transform that data. No restriction is placed on the length of the statement. An indication that the delineation (for example: limits and information) of a feature is known. [Desc] NA A general evaluation of the quality of a feature assessment, as a category. [Desc] NA A general evaluation of the coverage quality of a survey, as a category. [Desc] See possibly accompanying Attribute: 'Position Quality Category' for additional survey-related information. One or more intended attribute domain values for one or more enumeration or codelist attributes that are not currently valid members of their respective attribute ranges. [Desc] The actual attribute domain values may have been previously, or may become in the future, valid members of the attribute domain range. The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8. An indication that a feature is a community of administrative units, which does not belong to a common local administrative unit. [Desc] this community and the administrative unit still belong to the same level. The level of the administrative division defined by the hierarchical order in a geopolitical entity. [Desc] The first level is understood as the first level below a sovereign state or similar. The designation of the subnational administration unit. [Desc] For example, 'Department' or 'County'. The controlling authority responsible for a facility or site. [Desc] Controlling authorities may be distinguished by organizational level (for example: national, sub-national, or military district) and/or type (for example: private or public). The basis upon which an administratively subordinate division of a geopolitical entity (country) is established, other than for the purpose of governing as a unique subordinate division. [Desc] Non-governance purposes for which an administrative division may be established include, for example: economic development, postal service, utility provision, or data collection. A description of the unique administrative circumstances of an administrative region, if any. [Desc] For example, the type(s) of activities that are administered and the nature of the control(s) exerted. The average number of inhabitants residing within an area, per unit area. [Desc] NA The number of people within an area (for example: an administrative or built-up area). [Desc] NA A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart.

The type of a geographic name based on its scope of use, quality of source and/or its transliteration status. [Desc] NA The character set used for the display of characters with diacritics and special characters in a geographic name. [Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

[Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB).

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River').

[Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side.

[Desc] NA The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language.

[Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack.

[Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

[Desc] Includes actual operations, operational capability, and planned or proposed man-made structures. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

[Desc] The Munsell system is based on a colour solid, or approximately a colour sphere, which has a neutral gray central axis grading from white at the top to black at the bottom. This property of lightness is called value. Around the circumference or equator of the solid are the ten major hues, each of which is divided into ten numbered divisions, so that 5 marks the middle of the hue, and 10 marks the boundary between one hue and the next. Thus, any particular hue can be designated by a number and a letter such as 5R or 10YR. Any single vertical section through the neutral gray axis and a particular hue constitutes a colour chart on which the colors grade in value from light at the top to dark at the bottom, and in chroma (degree of saturation) from gray at one edge to the most vivid colors out at the margin. Both value and chroma are numbered so any particular colour can be given a numerical designation representing hue, value, and chroma such as 5R 6/4 and 10YR 8/2.

[Desc] NA The slope (rate of upward inclination of the surface from the horizontal) of the surface of a feature (for example: the terrain or a waterbody floor). [Desc] The (percent) slope is determined as the change in height divided by the horizontal distance over which the change takes place, multiplied by one hundred: ((h2-h1)/d)*100. Generally the slope is determined along the primary alignment of a feature (its established direction of flow or use; for example: a road, a railway, a ridge line, and/or a bridge).

[Desc] NA The character set used for the display of characters with diacritics and special characters in a geographic name. [Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

[Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB).

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. The type of a geographic name based on its scope of use, quality of source and/or its transliteration status. [Desc] NA The character set used for the display of characters with diacritics and special characters in a geographic name. [Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side.

[Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the accuracy of the vertical position of a feature, as a category. [Desc] NA The method by which the absolute horizontal accuracy was derived. [Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability.

One or more intended attribute domain values for one or more enumeration or codelist attributes that are not currently valid members of their respective attribute ranges. [Desc] The actual attribute domain values may have been previously, or may become in the future, valid members of the attribute domain range. The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

[Desc] NA The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The physical characteristic(s) (for example: particle size, morphology or consistency) of the primary type of material composing a feature. [Desc] The basis for 'primary' may be, for example, compositional dominance or structural organization. The general colour of a waterbody sediment based on the Geological Society of America (GSA) rock colour chart and the Munsell colour system. [Desc] The Munsell system is based on a colour solid, or approximately a colour sphere, which has a neutral gray central axis grading from white at the top to black at the bottom. This property of lightness is called value. Around the circumference or equator of the solid are the ten major hues, each of which is divided into ten numbered divisions, so that 5 marks the middle of the hue, and 10 marks the boundary between one hue and the next. Thus, any particular hue can be designated by a number and a letter such as 5R or 10YR. Any single vertical section through the neutral gray axis and a particular hue constitutes a colour chart on which the colors grade in value from light at the top to dark at the bottom, and in chroma (degree of saturation) from gray at one edge to the most vivid colors out at the margin. Both value and chroma are numbered so any particular colour can be given a numerical designation representing hue, value, and chroma such as 5R 6/4 and 10YR 8/2. Colour names are based on the Inter-Society Color Council-National Bureau of Standards system of names. The primary type(s) of material composing a feature, exclusive of the surface.

[Desc] The basis for 'primary' may be, for example, compositional dominance or structural organization. The soil type as specified by the Unified Soil Classification System (USCS). [Desc] NA The slope (rate of upward inclination of the surface from the horizontal) of the surface of a feature (for example: the terrain or a waterbody floor). [Desc] The (percent) slope is determined as the change in height divided by the horizontal distance over which the change takes place, multiplied by one hundred: ((h2-h1)/d)*100. Generally the slope is determined along the primary alignment of a feature (its established direction of flow or use; for example: a road, a railway, a ridge line, and/or a bridge). In those cases where the primary alignment is essentially horizontal (for example, a beach, a watercourse bank, or a cut) the surface slope is typically determined at right angles to the primary alignment.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language.

[Desc] NA The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the accuracy of the vertical position of a feature, as a category. [Desc] NA The method by which the absolute horizontal accuracy was derived. [Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability.

A general evaluation of the horizontal accuracy of the geographic position of a feature, as a category. [Desc] NA A narrative or other textual description that records a general assessment of the quality of a resource (for example: a data instance, a data set or a data processing activity). [Desc] The quality of a data resource is dependent on the data providers knowledge regarding the lineage of the data and the processes that have been used to transform that data. No restriction is placed on the length of the statement. An indication that the delineation (for example: limits and information) of a feature is known.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

[Desc] NA The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof.

[Desc] The basis for 'primary' may be, for example, compositional dominance or structural organization. The general colour of a waterbody sediment based on the Geological Society of America (GSA) rock colour chart and the Munsell colour system. [Desc] The Munsell system is based on a colour solid, or approximately a colour sphere, which has a neutral gray central axis grading from white at the top to black at the bottom. This property of lightness is called value. Around the circumference or equator of the solid are the ten major hues, each of which is divided into ten numbered divisions, so that 5 marks the middle of the hue, and 10 marks the boundary between one hue and the next. Thus, any particular hue can be designated by a number and a letter such as 5R or 10YR. Any single vertical section through the neutral gray axis and a particular hue constitutes a colour chart on which the colors grade in value from light at the top to dark at the bottom, and in chroma (degree of saturation) from gray at one edge to the most vivid colors out at the margin. Both value and chroma are numbered so any particular colour can be given a numerical designation representing hue, value, and chroma such as 5R 6/4 and 10YR 8/2. Colour names are based on the Inter-Society Color Council-National Bureau of Standards system of names. The primary type(s) of material composing a feature, exclusive of the surface.

[Desc] NA The slope (rate of upward inclination of the surface from the horizontal) of the surface of a feature (for example: the terrain or a waterbody floor). [Desc] The (percent) slope is determined as the change in height divided by the horizontal distance over which the change takes place, multiplied by one hundred: ((h2-h1)/d)*100. Generally the slope is determined along the primary alignment of a feature (its established direction of flow or use; for example: a road, a railway, a ridge line, and/or a bridge). In those cases where the primary alignment is essentially horizontal (for example, a beach, a watercourse bank, or a cut) the surface slope is typically determined at right angles to the primary alignment.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB).

[Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name.

NA [Desc] NA A borehole housing devices to minimize electrolytic corrosion of metallic pipelines, tanks, and other facilities in contact with the ground. [Desc] Cathodic protection wells (boreholes), sometimes called 'deep groundbeds', are widely installed to protect metallic objects in contact with the ground from electrolytic corrosion. Such objects include petroleum, natural gas, and water pipelines, and related storage facilities; power lines$$$$$ telephone cables$$$$$ and switchyards. Cathodic protection wells are sometimes used to control electrolytic corrosion in large water wells.

[Desc] Disposal wells typically are subject to regulatory requirements to avoid the contamination of freshwater aquifers. A well drilled as part of an Enhanced Oil Recovery (EOR) activity to increase the amount of crude oil that can be extracted from an oil field. [Desc] Using EOR (also termed 'tertiary recovery'), 30 to 60 percent, or more, of the reservoir's original oil can be extracted compared with 20 to 40 percent using primary and secondary recovery. Enhanced oil recovery is achieved by gas injection, chemical injection, ultrasonic stimulation, microbial injection, or thermal recovery (which includes cyclic steam, steamflooding, and fireflooding). A well into which water, other liquids, or gases are injected instead of being pumped out. [Desc] Injection wells are used in petroleum production. Steam, carbon dioxide, water, and other substances can be injected into an oil-producing unit in order to maintain reservoir pressure, heat the oil or lower its viscosity, thus allowing it to flow to a producing well nearby. Injection wells may also be used for waste water dumping, in which waste water is injected into the ground between impermeable layers of rocks to avoid polluting fresh water supplies. A well that is used to observe changes in groundwater levels over a period, or more specifically during a pumping test. [Desc] Pumping does not normally take place from observation wells, which are typically of relatively small diameter. A vertical shaft that after installation of the requisite weapon and associated test equipment is blocked (excepting equipment power and signal cables) to prevent the escape of post-explosion residue (for example: radioactive debris). [Desc] Most nuclear weapon states have constructed underground testing facilities similar to the U.S. Nevada Test Site including numerous boreholes used in weapons development and proof testing. Typical boreholes are 1 to 3 metres (roughly 48 to 120 inches) in diameter and 213 to 762 metres (600 to 2,500 feet) in depth. A wellbore that was not brought into service due to the excessive presence of radioactive materials in subsurface strata. [Desc] Subsurface formations may contain low levels of radioactive materials such as uranium and thorium and their daughter products, radium 226 and radium 228. Such Naturally Occurring Radioactive Material (NORM) typically appears in trace amounts and can be brought to the surface through oil or gas wells (for example: when fluids that are present in the radioactive formation are pumped out of the well, or when natural gas contains radon gas, a radium daughter). A well intended for the purpose of supporting production in an existing field. [Desc] Such wells are drilled for the following specific purposes: gas injection (natural gas, propane, butane, flue gas, or carbon dioxide); water injection$$$$$ steam injection$$$$$ air injection$$$$$ saltwater disposal$$$$$ water supply for injection (termed a 'source well')$$$$$ observation$$$$$ or injection for in-situ combustion (termed 'fire flooding'). A well that is used to pump materials (for example: liquefied petroleum gas) into an underground reservoir or cavern for later retrieval. [Desc] NA A well that is drilled in order to determine the types and layering of subsurface strata. [Desc] Such wells may be drilled to: evaluate subsurface rock formations for suitability for oil and/or gas production, solution mining, geothermal development, underground gas storage or brine disposal; investigate subsurface conditions in problem areas$$$$$ or gather information for research (for example: retrieval of ice cores) or construction projects.

[Desc] The operational capacity may not be authorized for various reasons, such as newly installed and not yet commissioned or certified, or operational but has been taken out of service for non-technical reasons, awaiting certification or commissioning status. Fully capable of operation. [Desc] The schedule of operations may be indeterminate or unknown. Functional, but operating with only partial capability for some reason. [Desc] Parts of the man-made structure are not in operation; or, the operation is running below capacity. Not in operation due to it being non-functional and operation is not scheduled to be restored. [Desc] NA Future operations are scheduled.

[Desc] Incorporates site preparations, building of new construction and the renovation or repair of existing structures. The man-made structure has undergone a systematic selective removal of components. [Desc] Low value components and/or equipment may remain. The man-made structure cannot be repaired without a great deal of time and effort. The man-made structure has undergone complete destruction and is in a state of total disrepair. [Desc] Destruction may be a consequence of military action, natural disaster, planned demolition or a long period of no maintenance. A destroyed man-made structure can only be restored by complete reconstruction. The man-made structure is complete and intact. [Desc] The man-made structure may or may not be in operation or use. The man-made structure is left in place to deteriorate. [Desc] The man-made structure has been abandoned and no maintenance or repairs are being carried out. While the structure is physically intact, no signs of operation are visible. The man-made structure is damaged. [Desc] Damage may be a consequence of accident, military action, or natural disaster. The damaged man-made structure can be repaired. No Information [Desc] NA Not Applicable [Desc] NA Other [Desc] NA NA [Desc] NA The well is in operation for its intended purpose (for example: natural gas recovery or waste disposal) or the borehole is serving its intended function. [Desc] NA The wellhead is not immediately accessible from the surface, being covered by a significant amount of overburden. [Desc] NA The wellbore is being drilled. [Desc] NA The wellbore has not encountered hydrocarbons in economically producible quantities. [Desc] Most wells contain salt water in some zones. In addition, the wellbore usually encounters small amounts of crude oil and natural gas. Whether the well is a 'duster' depends on many factors of the economic equation, including proximity to transport and processing infrastructures, local market conditions, expected completion costs, tax and investment recovery conditions of the jurisdiction and projected oil and gas prices during the productive life of the well. The mineral rights lease governing the operation of the well has expired. [Desc] NA The well or borehole is planned but drilling has not yet commenced. [Desc] NA The well has permanently ceased production or the borehole ceased serving its intended function and has been plugged. [Desc] Different regulatory bodies have differing requirements for plugging operations, typically requiring that cement plugs be placed and tested across any open hydrocarbon-bearing formations, across all casing shoes, across freshwater aquifers, and perhaps several other areas near the surface, including the top 6 to 15 metres (20 to 50 feet) of the wellbore. Unproductive drilling operations continued to a greater depth than that at which a potentially productive formation was found, and the well was subsequently completed in the shallower formation with the length of the well bore from the deepest depth at which the well is completed to the maximum depth drilled plugged to ensure against cross-strata fluid migration. [Desc] NA The well or borehole has been closed off, the well being shut so that it does not produce a fluid product of any kind, or the borehole is no longer serving its intended function. [Desc] NA The well has been capped off temporarily. [Desc] NA The well has temporarily ceased production or the borehole ceased serving its intended function, some or all recoverable equipment has been salvaged, but the site has been left in a state to readily enable the future resumption of operations. [Desc] NA The well has ceased production (for example: because there is insufficient hydrocarbon potential to complete the well, or production operations have drained the reservoir) or the borehole ceased serving its intended function (for example: injection operations are no longer necessary) and all recoverable equipment has been salvaged. [Desc] NA The well has not entered full production, being used only for the extraction of limited quantities. [Desc] NA The well has not yet been 'completed' by the addition of downhole pipe and equipment required to enable safe and efficient production.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8. The cross-sectional shape of a feature in the horizontal plane. [Desc] NA The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature.

The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature.

[Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

[Desc] NA The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL).

The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof.

[Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB).

[Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB).

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The vertical distance measured from the base to the top of the feature that gives the greatest value. [Desc] For example, the Height of Object of a two story building with a basement is three stories while the Height of Object of a man doesn't change as a result of standing in a trench whereas his Height Above Surface Level (based on the prevailing terrain surface level) may be considered to be correspondingly reduced by the depth of the trench. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack.

[Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

[Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

[Desc] NA The distance measured from ground or water level (uphill/upstream side of the feature) to the highest point of a feature located completely underground. [Desc] For example, in the case of an underground dwelling the least depth below surface level would be measured to its ceiling. The least depth below surface level may be located at ground or water level and therefore have a value of zero (for example: an opencast extraction mine, a terrain depression or a lake). For depths defined with respect to a time-varying water level, consideration should be given to the use of Attribute: 'Hydrographic Depth'.

[Desc] For example, a cable or a set of cables connected to opposite shores that are used to guide or propell a cable ferry across a body of water. Older ferries may be moved by poling, by currents or by people pulling the ferry along the stationary cable. Modern cable ferries use a winch either located on the vessel or on shore to propel it across the waterbody. A cable ferry usually operates on narrow rivers that have little or no marine traffic. A cable that is a barrier to movement. [Desc] For example, cable gates, cable fences and guard rail cables. Cable fences are a thick cable or cables securely locked across a vehicle access to prevent or control entry or exit providing a physical barrier against unauthorized vehicles and cable fences which usually consist of cables stretched between anchor posts.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

[Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

[Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language.

[Desc] As determined by IUCN Category VI. An area of land, with coast and sea as appropriate, where the interaction of people and nature over time has produced an area of distinct character with significant aesthetic, ecological, or cultural value, and often with high biological diversity. [Desc] Safeguarding the integrity of this traditional interaction is vital to the protection, maintenance, and evolution of such an area. As determined by IUCN Category V. An area of land or sea subject to active intervention for management purposes to meet the requirements of specific species. [Desc] A subset of IUCN Category IV. An area of land or sea possessing some outstanding or representative ecosystems, geological or physiological features and/or species, available primarily for scientific research or environmental monitoring. [Desc] As determined by IUCN Category Ia.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

[Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

[Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

[Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

The distance measured from ground or water level (uphill/upstream side of the feature) to the deepest point of the feature. [Desc] May be used to measure the depth of an inland waterbody (for example: a lake), the depth of a terrain surface depression or excavation (for example: a crevice or trench), the distance to the deepest point of a drilled feature (for example: a water well or borehole) or the distance to the deepest point of a feature located entirely underground (for example: a cave chamber). In the case of a feature located below a waterbody (for example: a non-water well) the reference surface is the waterbody bottom, rather than the waterbody surface. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language.

[Desc] NA The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

[Desc] NA Provided with one or more lattice frameworks of light bars (for example: wooden or metal) used as a support for crops (for example: fruit trees or vines). [Desc] NA The fields have no regular arrangement and/or pattern. [Desc] NA No Information [Desc] NA Not Applicable [Desc] NA Other [Desc] NA NA [Desc] NA Plants are grown in raised beds or listed rows (in the case of row crops) with water distributed throughout the field via ditches or pipes, and between the beds or rows using furrows. [Desc] Where ditches are used, manually controlled siphon tubes may be used move water from the main ditch to the furrow. When pipes are used, water flow can be controlled by turning it on or off at the local source or by using automatic or manually controlled gates to transfer it from one set of ditches to another. Unless the field is small or very level, parts of it may suffer from water-logging while other parts may be too dry. Depending on heat, wind, and soil permeability, much water may be lost before it can benefit the plants. Water is piped to one or more central locations within the field and distributed by overhead high-pressure sprinklers or guns or by lower-pressure sprays. [Desc] A system utilizing sprinklers, sprays, or guns mounted overhead on permanently installed risers is often referred to as a 'solid-set' irrigation system. Manually assembled systems of piping that are broken down to permit tillage and harvesting are sometimes called 'hand set' or 'hand move pipe'. Some sprinklers can also be hidden below ground level, if aesthetics is a concern, and pop up in response to increased water pressure. Sprinklers that spray in a fixed pattern are generally called sprays or spray heads. Higher pressure sprinklers that rotate are called rotors and are driven by a ball drive, gear drive, or impact mechanism. Rotors can be designed to rotate in a full or partial circle. Guns are similar to rotors, except that they generally operate at very high pressures. One drawback of overhead irrigation is that much water can be lost because of high winds or evaporation, and irrigating the entire field uniformly can be difficult or tedious if the system is not properly designed. Water remaining on plants' leaves may promote fungal and other diseases. A form of overhead irrigation consisting of several segments of pipe (usually galvanized steel or aluminum) joined together and supported by trusses, mounted on wheeled towers with sprinklers positioned along its length, the system moving in a circular pattern and fed with water from the pivot point at the center of the arc. [Desc] Most center pivot systems now have drops hanging from a u-shaped pipe called a gooseneck attached at the top of the pipe with sprinkler heads that are positioned a few feet (at most) above the crop, thus limiting evaporative losses. Drops can also be used with drag hoses or bubblers that deposit the water directly on the ground between crops. The crops are planted in a circle to conform to the center pivot. A form of overhead irrigation similar to center pivot irrigation in which the equipment is configured to move in a straight line, where the water is pulled from a central ditch.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

[Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River').

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

[Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

[Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

[Desc] Includes actual operations, operational capability, and planned or proposed man-made structures. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters.

The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB).

An administrative unit not associated with an armed force. [Desc] NA Administered on behalf all members of a community, rather than restricted to an individual or corporation. [Desc] NA No Information [Desc] NA Not Applicable [Desc] NA Other [Desc] NA NA [Desc] NA A thin, curved (for example concrete or masonry) dam structure which is built to curve upstream so that the force of the water against it squeezes the arch, compressing and strengthening the structure and pushing it into the ground. [Desc] An arch dam is a good dam type for a narrow gorge in a mountainous area with steep walls of rock. An arch dam generally has steel rods or prestressed steel cables reinforcements and therefore requires less concrete than does a gravity dam or arch-gravity dam. However, the bedrock in the foundation and abutments must be sound to withstand the pressure of the water. An Embankment dam which is built with asphalt concrete core. The majority of such dams are built with rock and/or gravel as the main fill material. [Desc] Almost 100 dams of this design have now been built worldwide since the first such dam was completed in 1962. The type of asphalt used is a viscoelastic-plastic material that can adjust to the movements and deformations imposed on the embankment as a whole, and to settlements in the foundation. The flexible properties of the asphalt make such dams especially suited in earthquake regions. Beavers create dams primarily out of mud and sticks to flood a particular habitable area. [Desc] By flooding a parcel of land, beavers can navigate below or near the surface and remain relatively well hidden or protected from predators. The flooded region also allows beavers access to food, especially during the winter. A water-tight dam supported at intervals on the downstream side by a series of buttresses or supports. [Desc] The dam wall may be flat or curved. A (usually temporary) barrier constructed to exclude water from an area that is normally submerged. Made commonly of wood, concrete or steel sheet piling, cofferdams are used to allow construction on the foundation of permanent dams, bridges, and similar structures. When the project is completed, the cofferdam may be demolished or removed. [Desc] See also causeway and retaining wall. Common uses for cofferdams include construction and repair of off shore oil platforms. In such cases the cofferdam is fabricated from sheet steel and welded into place under water. Air is pumped into the space, displacing the water allowing a dry work environment below the surface. Upon completion the cofferdam is usually deconstructed unless the area requires continuous maintenance. Dams, which are constructed as a simple embankment of well compacted earth. A homogeneous rolled-earth dam is entirely constructed of one type of material but may contain a drain layer to collect seep water. A zoned-earth dam has distinct parts or zones. [Desc] An outdated method of zoned earth dam construction utilized a hydraulic fill to produce a watertight core. Rolled-earth dams may also employ a watertight facing or core in the manner of a rock-fill dam. A massive artificial water barrier. It is typically created by the emplacement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay and/or rock. It has a semi-permanent waterproof natural covering for its surface, and a dense, waterproof core. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than the use of a cementing substance. [Desc] The force of the impoundment creates a downward thrust upon the mass of the dam, greatly increasing the weight of the dam on its foundation. In a gravity dam, stability is secured by making it of such a size and shape that it will resist overturning, sliding and crushing at the toe. The dam will not overturn provided that the moment around the turning point, caused by the water pressure is smaller than the moment caused by the weight of the dam. This is the case if the resultant force of water pressure and weight falls within the base of the dam. [Desc] However, in order to prevent tensile stress at the upstream face and excessive compressive stress at the downstream face, the dam cross section is usually designed so that the resultant falls within the middle at all elevations of the cross section (the core). For this type of dam, impervious foundations with high bearing strength are essential. A dam constructed with more than one contiguous arch or plane. [Desc] NA An embankment of compacted free-draining granular earth with an impervious zone. The earth utilized often contains a large percentage of large particles hence the term rock-fill. The impervious zone may be on the upstream face and made of masonry, concrete, plastic membrane, steel sheet piles, timber or other material. The impervious zone may also be within the embankment in which case it is referred to as a core. [Desc] In the instances where clay is utilized as the impervious material the dam is referred to as a composite dam. A type of dam briefly experimented with in around the turn of the 19th-20th Century which uses steel plating (at an angle) and load bearing beams as the structure. [Desc] Intended as permanent structures, steel dams were an (arguably failed) experiment to determine if a construction technique could be devised that was cheaper than masonry, concrete or earthworks, but sturdier than timber crib dams. Erected of heavy timbers or dressed logs in the manner of a log house and the interior filled with earth or rubble. [Desc] Timber dams were widely used in the early part of the industrial revolution and in frontier areas due to ease and speed of construction. Rarely built in modern times by humans because of relatively short lifespan and limited height to which they can be built, timber dams must be kept constantly wet in order to maintain their water retention properties and limit deterioration by rot, similar to a barrel. The locations where timber dams are most economical to build are those where timber is plentiful, cement is costly or difficult to transport, and either a low head diversion dam is required or longevity is not an issue. Timber dams were once numerous, especially in the North American west, but most have failed, been hidden under earth embankments or been replaced with entirely new structures. Two common variations of timber dams were the crib and the plank. No Information [Desc] NA Not Applicable [Desc] NA Other [Desc] NA NA [Desc] NA Vertical. [Desc] Typically used in concrete construction. Slopes away from vertical towards the reservoir. [Desc] Typically results from earthen construction. No Information [Desc] NA Not Applicable [Desc] NA Other [Desc] NA NA [Desc] NA A large dam that ensures that a waterway is navigable by ensuring sufficient upriver channel depth and that is bypassed by one or more locks. [Desc] Typically more than 15 metres tall, navigation dams normally permit water flow by means of spillways or gates with roller and tainter gates being the most commonly installed. Most navigation pools in the United States are maintained at a constant minimum water depth of 3 metres (9 feet). The installation of navigation dams permit river vessels to use a series of locks to 'step' up or down a river from one water level to another. A dam whose reservoir is regulated to accomplish flood control. [Desc] It may also provide a source of water for irrigation and/or hydroelectric power. For example, the Grand Coulee Dam. A dam which is intended to produce electrical power from the potential energy of dammed water driving a water turbine and generator. [Desc] To boost the power generation capabilities of a dam, the water may be run through a large pipe called a penstock before the turbine. A variant on this simple model uses pumped storage hydroelectricity to produce electricity to match periods of high and low water. A small overflow-type dam commonly used to raise the upstream water level of a river or stream. [Desc] Typically less than 15 metres tall, water flows over the top of a weir although some weirs have sluice gates which release water at a level below the top of the weir. The crest of an overflow spillway on a large dam is often called a weir. Weirs have traditionally been used to create mill ponds or to provide adequate water supply to maintain levels in an adjacent canal. Weirs may be associated with locks to permit the passage of boats around the weir.

The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

The slope (rate of upward inclination of the surface from the horizontal) of the surface of a feature (for example: the terrain or a waterbody floor). [Desc] The (percent) slope is determined as the change in height divided by the horizontal distance over which the change takes place, multiplied by one hundred: ((h2-h1)/d)*100. Generally the slope is determined along the primary alignment of a feature (its established direction of flow or use; for example: a road, a railway, a ridge line, and/or a bridge).

An accentuated subset of the contour lines, typically every fourth or fifth contour line depending on the contour interval, as an aid in identifying contour lines of different elevations. [Desc] It is typically depicted by increased line weight. With few exceptions, index contour lines are continuous throughout a map even though the contour lines may coalesce (to carrying contour lines) because of steep slopes. One of the three or four contour lines between adjacent index contour lines. [Desc] It is typically depicted with about half the line weight of an index contour line.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8. The angular distance in the horizontal plane measured from true north (0 degrees) clockwise to the major axis of the feature. [Desc] If the feature is square, the axis 0 up to 90 degrees is recorded. If the feature is circular, 360 degrees is recorded. The controlling authority responsible for a facility or site. [Desc] Controlling authorities may be distinguished by organizational level (for example: national, sub-national, or military district) and/or type (for example: private or public). The cross-sectional shape of a feature in the horizontal plane. [Desc] NA The side(s) of a feature that produce the greatest visual significance and/or reflectivity potential.

The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself. The vertical distance measured from the base to the top of the feature that gives the greatest value. [Desc] For example, the Height of Object of a two story building with a basement is three stories while the Height of Object of a man doesn't change as a result of standing in a trench whereas his Height Above Surface Level (based on the prevailing terrain surface level) may be considered to be correspondingly reduced by the depth of the trench. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. An indication that a feature is permanent. [Desc] Temporary features last, or are meant to last, for a limited time only. The physical condition of a man-made structure, as a whole, including the inside and/or outside of the structure and any contained and/or associated equipment.

The type of a geographic name based on its scope of use, quality of source and/or its transliteration status. [Desc] NA The character set used for the display of characters with diacritics and special characters in a geographic name. [Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language.

[Desc] It is used in terrain depressions of extremely low relief to assist the proper depiction of the slope of the land. It is typically depicted with perpendicular ticks on the descending side of the depression auxiliary contour line and as a screened line so that it is distinguishable from depression index and depression intermediate contour lines and not unduly prominent. A closed contour line substituted for a normal depression auxiliary contour line whenever there is a question as to its reliability (for example: due to glacial ice or cloud cover). [Desc] It is typically depicted as a broken line while maintaining depression auxiliary contour line weight and associated perpendicular ticks. A line that is neither a contour line nor a form line nor is intended as a connector line. [Desc] May be used to support generalized depiction of hyposography but does not necessarily follow points of equal elevation.

NA [Desc] NA An all-weather facility used for the performance testing of a dismounted jet engine that includes an augmenter tube and an overall enclosure designed to minimize noise exposure by test personnel and others in the vicinity. [Desc] The facility acts as a large fluid-driven pump. Engine exhaust gases, leaving the nozzle as a high-velocity, high-temperature, relatively small diameter jet, are directed into the augmenter tube. An expanding shear layer develops around the jet, pulling along a layer of cool ambient air. Momentum and energy are transferred to this augmentation air, decreasing the velocity and temperature of the jet. The overall structure generally consists of an intake stack, a test enclosure, the blast augmenter tube and an exhaust ramp and/or stack. An all-weather noise-abatement facility for conducting ground run-up testing of installed jet engines and/or making final adjustments and tuning the engines after overhauls. [Desc] It consists of a tall hangar with sound-proof walls that may contain either the entire aircraft (in the case of wing-mounted engines) or just the tail section (in the case of tail-mounted engines). Prominently placed are multiple stacks (chimneys) for air inlet and exhaust; there may be additional horizontal tube-exhausts along the rear wall. The exhaust stacks and/or tubes contain sound-silencers and they are linked to augmenter tubes placed behind the jet engine(s) being tested in order to gather all exhausts. An open-air structure for testing the performance of an upright (vertically mounted) rocket engine that includes a blast deflector and/or cooling mechanisms (for example: water sprays) to handle the substantial amount of high-temperature exhaust gases produced during operation. [Desc] The structure is usually associated with substantial liquid fuel (for example: liquid hydrogen or kerosene) and oxidant (for example: liquid oxygen) tanks and associated pipes. It is typically located distant from centers of population due to the intense sound produced during test firing. A structure, usually open-air, for testing the performance of a horizontally mounted rocket engine. [Desc] The structure is sufficient to mount the engine (for example: a solid-fuel booster) and safely direct the exhaust. There may be a concrete pan to provide a degree of protection to the local surface. In the case of a liquid-fueled engine there may be associated small tanks containing fuel and oxidizer. In some cases the entire structure may consist of a shed with a side that is either permanently or temporarily opened during testing.

In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. The type of a geographic name based on its scope of use, quality of source and/or its transliteration status. [Desc] NA The character set used for the display of characters with diacritics and special characters in a geographic name. [Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB).

[Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of').

NA [Desc] NA The surface material is removed in successive parallel strips to expose the mineral, the spoil from each new strip being placed in the previously excavated one. [Desc] They are used in generally flat terrain and are commenced with a trench or 'box cut' made through the overburden to expose a portion of the mineral seam. This trench is extended, in a series of cuts 30 to 60 metres wide, to the limits of the property in the strike direction. After mineral removal, a second cut is made parallel to the first one, and the overburden material from this cut is placed in the void of the first cut.

[Desc] NA An open-air excavation for the extraction of stone intended principally for use in construction. [Desc] NA The surface material is removed in a strip along the side of a hill to expose the mineral. [Desc] They are used where a mineral seam outcrops in rolling or hilly terrain. The method consists of removing the overburden above the mineral seam and then, starting at the outcrop and proceeding along the hillside, creating a bench around the hill. In the past, the blasted overburden spoil was simply shoved down the hill; currently, soil is either carried down the mountain to fill a chosen valley in horizontal layers or is replaced on the working bench itself in places where the mineral has been removed. If the break-even stripping ratio remains favourable, further cuts into the hillside will be made. Otherwise, if there are sufficient reserves under the knob of the hill, the mineral may be recovered by underground mining or by augering.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge).

The physical characteristic(s) (for example: particle size, morphology or consistency) of the primary type of material composing a feature. [Desc] The basis for 'primary' may be, for example, compositional dominance or structural organization. The general colour of a waterbody sediment based on the Geological Society of America (GSA) rock colour chart and the Munsell colour system. [Desc] The Munsell system is based on a colour solid, or approximately a colour sphere, which has a neutral gray central axis grading from white at the top to black at the bottom. This property of lightness is called value. Around the circumference or equator of the solid are the ten major hues, each of which is divided into ten numbered divisions, so that 5 marks the middle of the hue, and 10 marks the boundary between one hue and the next. Thus, any particular hue can be designated by a number and a letter such as 5R or 10YR. Any single vertical section through the neutral gray axis and a particular hue constitutes a colour chart on which the colors grade in value from light at the top to dark at the bottom, and in chroma (degree of saturation) from gray at one edge to the most vivid colors out at the margin. Both value and chroma are numbered so any particular colour can be given a numerical designation representing hue, value, and chroma such as 5R 6/4 and 10YR 8/2.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River').

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB).

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

[Desc] NA The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL).

For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB).

[Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A location that normally does not appear as a specific, characterized object but that has either a name that is required to be displayed or other specific information associated with that location. [Desc] For example, the name of the Alps or the Sahara. A 0-dimensional geometric primitive, representing a position. [Desc] NA The area within the delineation of the feature. [Desc] NA The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the accuracy of the vertical position of a feature, as a category. [Desc] NA The method by which the absolute horizontal accuracy was derived. [Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the horizontal accuracy of the geographic position of a feature, as a category. [Desc] NA A narrative or other textual description that records a general assessment of the quality of a resource (for example: a data instance, a data set or a data processing activity). [Desc] The quality of a data resource is dependent on the data providers knowledge regarding the lineage of the data and the processes that have been used to transform that data. No restriction is placed on the length of the statement. An indication that the delineation (for example: limits and information) of a feature is known. [Desc] NA A general evaluation of the quality of a feature assessment, as a category. [Desc] NA A general evaluation of the coverage quality of a survey, as a category. [Desc] See possibly accompanying Attribute: 'Position Quality Category' for additional survey-related information. One or more intended attribute domain values for one or more enumeration or codelist attributes that are not currently valid members of their respective attribute ranges. [Desc] The actual attribute domain values may have been previously, or may become in the future, valid members of the attribute domain range. The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8.

[Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

[Desc] NA A fracture or zone of fractures in the Earth's crust along which there has been displacement of the sides relative to one another and parallel to the fracture possibly resulting in the relative displacement and loss of continuity of the rocks on either side of it. [Desc] Various types of geologic faults can be characterized by such factors as: the loss of continuity of the rock surfaces on either side of the fracture, the amount of dip, the lie of the strike line relative to the general structural trend of the nearby region, and extension versus compression. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart.

NA [Desc] NA A gliding plane between two rock masses, also known as a basal detachment fault. [Desc] It is a shallow dipping fault. Typically faults or folds in rocks above and below the decollement do not extend across it. A fault that vertically thins and horizontally extends portions of the Earth's crust and/or lithosphere. [Desc] In most cases such a fault is also a normal fault, but may be rotated to have a shallower geometry normally associated with a thrust fault. A fault in which the hanging wall appears to have moved downward relative to the footwall. The angle of dip is usually 45 to 90 arc degrees. [Desc] Normal faults occur where two blocks of rock are pulled apart, as by tension. A fault that runs obliquely to, rather than parallel to or perpendicular to, the strike of the constituent rocks or dominant structure. [Desc] NA A portion of a strike-slip fault that is offset along the strike such as to create a gap, for example, a left-stepping bend on a sinistral fault; a zone of extension or transtension is generated. [Desc] Also known as extensional stepovers, releasing bends often form pull-apart basins or rhombochasms. A portion of a strike-slip fault that forms where the orientation of a strike-slip fault becomes oblique to the regional slip vector causing local compression or uplift. [Desc] They also form where two segments of a strike-slip fault overlap, and the relay zone between the segments experiences transpression. Restraining bends often form positive flower structures or pop-up ridges. A fault along which the hanging wall has moved upward relative to the footwall. [Desc] Reverse faults occur where two blocks of rock are forced together by compression. A fault located within a shear zone. [Desc] A shear zone is a tabular to sheetlike, planar or curviplanar zone composed of rocks that are more highly strained than rocks adjacent to the zone. A fault on which the movement is parallel to the fault's strike. [Desc] NA A fault with a dip of 45 arc degrees or less over much of its extent, on which the hanging wall appears to have moved upward relative to the footwall.

[Desc] Its subtypes include (but are not limited to): GM_LineString, GM_LineSegment, GM_GeodesicString, GM_Geodesic, GM_ArcString, and GM_Arc. The area within the delineation of the feature. [Desc] NA The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability.

A general evaluation of the horizontal accuracy of the geographic position of a feature, as a category. [Desc] NA A narrative or other textual description that records a general assessment of the quality of a resource (for example: a data instance, a data set or a data processing activity).

[Desc] The actual attribute domain values may have been previously, or may become in the future, valid members of the attribute domain range. The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8. The type of a geomorphic feature based on the local configuration of terrain slope(s) and aspect(s). [Desc] NA The slope (rate of upward inclination of the surface from the horizontal) of the surface of a feature (for example: the terrain or a waterbody floor). [Desc] The (percent) slope is determined as the change in height divided by the horizontal distance over which the change takes place, multiplied by one hundred: ((h2-h1)/d)*100. Generally the slope is determined along the primary alignment of a feature (its established direction of flow or use; for example: a road, a railway, a ridge line, and/or a bridge). In those cases where the primary alignment is essentially horizontal (for example, a beach, a watercourse bank, or a cut) the surface slope is typically determined at right angles to the primary alignment. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River').

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

[Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

[Desc] NA The area within the delineation of the feature. [Desc] NA The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the accuracy of the vertical position of a feature, as a category. [Desc] NA The method by which the absolute horizontal accuracy was derived. [Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the horizontal accuracy of the geographic position of a feature, as a category. [Desc] NA A narrative or other textual description that records a general assessment of the quality of a resource (for example: a data instance, a data set or a data processing activity).

No restriction is placed on the length of the statement. An indication that the delineation (for example: limits and information) of a feature is known. [Desc] NA A general evaluation of the quality of a feature assessment, as a category. [Desc] NA A general evaluation of the coverage quality of a survey, as a category. [Desc] See possibly accompanying Attribute: 'Position Quality Category' for additional survey-related information. One or more intended attribute domain values for one or more enumeration or codelist attributes that are not currently valid members of their respective attribute ranges. [Desc] The actual attribute domain values may have been previously, or may become in the future, valid members of the attribute domain range. The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

[Desc] NA The degree of impact of vegetation on trafficability, based on the percent trafficability reduction from a smooth, vegetation-free terrain surface (zero percent reduction). [Desc] Vegetation reduces trafficability by requiring that either it must be 'overridden' (for example: scrub by a battle tank) or bypassed (for example: orchard trees by an infantryman). A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart.

[Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

[Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. An indication that a feature may serve as a navigation landmark, allowing for rapid and positive orientation of a navigator. [Desc] Its size, shape, and/or location make it prominent in relation to its surroundings, and it is therefore easily recognized from the surface and/or from the air. The physical condition of a man-made structure, as a whole, including the inside and/or outside of the structure and any contained and/or associated equipment. [Desc] The physical condition applies to any phase of the life cycle of a man-made structure from construction to destruction. Examples of man-made structures include roads, canals, buildings, towers, aerodromes and facilities. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end.

[Desc] NA The character set used for the display of characters with diacritics and special characters in a geographic name. [Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB).

[Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

[Desc] Its subtypes include (but are not limited to): GM_PolyhedralSurface (which aggregates GM_Polygon). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the accuracy of the vertical position of a feature, as a category. [Desc] NA The method by which the absolute horizontal accuracy was derived. [Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself.

The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

[Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

No Information [Desc] NA Not Applicable [Desc] NA Other [Desc] NA NA [Desc] NA Plants are grown in raised beds or listed rows (in the case of row crops) with water distributed throughout the field via ditches or pipes, and between the beds or rows using furrows. [Desc] Where ditches are used, manually controlled siphon tubes may be used move water from the main ditch to the furrow. When pipes are used, water flow can be controlled by turning it on or off at the local source or by using automatic or manually controlled gates to transfer it from one set of ditches to another. Unless the field is small or very level, parts of it may suffer from water-logging while other parts may be too dry. Depending on heat, wind, and soil permeability, much water may be lost before it can benefit the plants. A form of overhead irrigation similar to center pivot irrigation in which the equipment is configured to move in a straight line, where the water is pulled from a central ditch. [Desc] NA A form of overhead irrigation in which a series of pipes, each with a wheel of about 1.5 metre diameter permanently affixed to its midpoint and sprinklers along its length, are coupled together at one edge of a field with water supplied (for example: by using a large hose) at one end of the series. After sufficient water has been applied the assembly is rotated either by hand or with a purpose-built mechanism, so that the sprinklers move approximately 10 metres across the field, following which the water supply is reconnected. The process is repeated until the opposite edge of the field is reached. [Desc] This system is less expensive to install than a center pivot, but much more labor intensive to operate, and it is limited in the amount of water it can carry. They are most often used for small or oddly-shaped fields, such as those found in hilly or mountainous regions, or in regions where labor is inexpensive. Water is applied slowly to the roots of plants, by depositing the water either on the soil surface or directly to the root zone, typically through the use of 'emitters' (which emit the water in a slow stream) or 'micro-sprinklers' (which spray water in a small area). [Desc] This type of system can be the most water-efficient method of irrigation, if managed properly, since evaporation and runoff are minimized. Drip irrigation is often combined with plastic mulch, further reducing evaporation. Drip irrigation can also be accomplished using porous clay vessels sunk into the soil and occasionally filled from a hose or bucket. Water is delivered from below, absorbed upwards, and the excess collected for recycling. [Desc] Typically, a solution of water and nutrients floods a container or flows through a trough for a short period of time, 10-20 minutes, and is then pumped back into a holding tank for reuse. It is similar in principle and action to subsurface drip irrigation, and results in mater and nutrient conservation. It is, for example, used in commercial greenhouse production, usually for potted plants. Large steps are cut into hillsides, supported by stone or concrete walls, and as water flows down the hillside it is channelled to each plot, most often by ditches. [Desc] Terracing is usually very labor-intensive, since fields are small and access to them may be steep and narrow making it difficult to mechanize the work. In addition, the walls need constant maintenance, especially in rainy climates. However, terracing does allow steep mountainsides to be used to grow plants (although it may be more cost-effective to use them only for animal pasturage). A form of overhead irrigation consisting of several segments of pipe (usually galvanized steel or aluminum) joined together and supported by trusses, mounted on wheeled towers with sprinklers positioned along its length, the system moving in a circular pattern and fed with water from the pivot point at the center of the arc. [Desc] Most center pivot systems now have drops hanging from a u-shaped pipe called a gooseneck attached at the top of the pipe with sprinkler heads that are positioned a few feet (at most) above the crop, thus limiting evaporative losses. Drops can also be used with drag hoses or bubblers that deposit the water directly on the ground between crops. The crops are planted in a circle to conform to the center pivot. Water is piped to one or more central locations within the field and distributed by overhead high-pressure sprinklers or guns or by lower-pressure sprays. [Desc] A system utilizing sprinklers, sprays, or guns mounted overhead on permanently installed risers is often referred to as a 'solid-set' irrigation system. Manually assembled systems of piping that are broken down to permit tillage and harvesting are sometimes called 'hand set' or 'hand move pipe'. Some sprinklers can also be hidden below ground level, if aesthetics is a concern, and pop up in response to increased water pressure. Sprinklers that spray in a fixed pattern are generally called sprays or spray heads. Higher pressure sprinklers that rotate are called rotors and are driven by a ball drive, gear drive, or impact mechanism. Rotors can be designed to rotate in a full or partial circle. Guns are similar to rotors, except that they generally operate at very high pressures. One drawback of overhead irrigation is that much water can be lost because of high winds or evaporation, and irrigating the entire field uniformly can be difficult or tedious if the system is not properly designed. Water remaining on plants' leaves may promote fungal and other diseases.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB).

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

[Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name.

The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument).

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge).

[Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

[Desc] May be used to measure the depth of an inland waterbody (for example: a lake), the depth of a terrain surface depression or excavation (for example: a crevice or trench), the distance to the deepest point of a drilled feature (for example: a water well or borehole) or the distance to the deepest point of a feature located entirely underground (for example: a cave chamber). In the case of a feature located below a waterbody (for example: a non-water well) the reference surface is the waterbody bottom, rather than the waterbody surface. The status of operation of a man-made structure, as a whole. [Desc] Includes actual operations, operational capability, and planned or proposed man-made structures. The distance measured from ground or water level (uphill/upstream side of the feature) to the highest point of a feature located completely underground.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

[Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature.

The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

[Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. NA [Desc] NA Not in operation due to it being non-functional and operation is not scheduled to be restored. [Desc] NA Future operations are scheduled. [Desc] NA Temporarily not in operation due to it being non-functional and operation is scheduled to be restored. [Desc] Usually an unscheduled loss of operation. Fully capable of operation. [Desc] The schedule of operations may be indeterminate or unknown. Functional, but operating with only partial capability for some reason. [Desc] Parts of the man-made structure are not in operation; or, the operation is running below capacity. No Information [Desc] NA Not Applicable [Desc] NA Other [Desc] NA A location, which is generally elevated, from which the surrounding area may be observed. [Desc] For example, it is easily accessible by vehicle, is free of obscuring vegetation, and the local topography allows for unobstructed viewing of distant features. A 0-dimensional geometric primitive, representing a position. [Desc] NA The area within the delineation of the feature. [Desc] NA The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the accuracy of the vertical position of a feature, as a category. [Desc] NA The method by which the absolute horizontal accuracy was derived. [Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the horizontal accuracy of the geographic position of a feature, as a category. [Desc] NA A narrative or other textual description that records a general assessment of the quality of a resource (for example: a data instance, a data set or a data processing activity).

No restriction is placed on the length of the statement. An indication that the delineation (for example: limits and information) of a feature is known. [Desc] NA A general evaluation of the quality of a feature assessment, as a category. [Desc] NA A general evaluation of the coverage quality of a survey, as a category. [Desc] See possibly accompanying Attribute: 'Position Quality Category' for additional survey-related information. One or more intended attribute domain values for one or more enumeration or codelist attributes that are not currently valid members of their respective attribute ranges. [Desc] The actual attribute domain values may have been previously, or may become in the future, valid members of the attribute domain range. The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8. An indication that a feature may serve as a navigation landmark, allowing for rapid and positive orientation of a navigator. [Desc] Its size, shape, and/or location make it prominent in relation to its surroundings, and it is therefore easily recognized from the surface and/or from the air. The physical condition of a man-made structure, as a whole, including the inside and/or outside of the structure and any contained and/or associated equipment. [Desc] The physical condition applies to any phase of the life cycle of a man-made structure from construction to destruction. Examples of man-made structures include roads, canals, buildings, towers, aerodromes and facilities. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. The type of a geographic name based on its scope of use, quality of source and/or its transliteration status. [Desc] NA The character set used for the display of characters with diacritics and special characters in a geographic name. [Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

[Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language.

[Desc] For example, the Soviet SS-1 (R-1, or Scud), SS-2 (R-2), SS-3, SS-4, and SS-5 missiles. A Soviet anti-aircraft surface-to-air missile (SAM) system, the first operational SAM deployed by the Soviet Union. [Desc] It was used only to defend Moscow. The missile uses a single liquid-fueled rocket motor. Its maximum speed is approximately Mach 2.5. Typical range for the missile is about 30 kilometres with a maximum altitude around 60,000 feet. A Soviet high-altitude surface-to-air guided missile (SAM) system, the most widely deployed and used air defence missile in history. [Desc] It is a two-stage missile, consisting of a solid-fuel booster and a storable liquid-fuel upper stage burning red fuming nitric acid as the oxidizer, and kerosene as the fuel. Each battalion consists of six semi-fixed trainable single-rail launchers for their missiles about 60 to100 metres apart, deployed in a hexagonal 'flower' pattern around the central radars and guidance systems. Typically another six missiles are stored on tractor-trailers near the center of the site. Typical range for the missile is about 45 kilometres, with a maximum altitude around 60,000 feet. A Soviet short-range surface-to-air missile (SAM) system designed to complement the S-25 Berkut (SA-1 'Guild') and V-75 (SA-2 'Guideline'). [Desc] The missiles are typically deployed on originally fixed, but later trailer-mounted, turrets containing two or four but can be carried ready-to-fire on Zil trucks in pairs or on tracked chassis carrying three missiles. It has a shorter effective range and lower engagement altitude than either of its predecessors and also flies slower, but due to its two-stage design it is more effective against more maneuverable targets. It is also able to engage lower flying targets than the previous systems, and being more modern it is much more resistant to ECM than the SA-2. The 5V24 (V-600) missiles reach around Mach 3 to 3.5 in flight, both stages powered by solid fuel rocket motors, and has an effective range of 25 kilometres. The SA-3, like the SA-2, uses radio command guidance. A Soviet long range, medium-to-high altitude surface-to-air missile (SAM) system. [Desc] The Transporter-Erector-Launcher (TEL) vehicles are tracked (modified AT-Ts) and carry two missiles each on an elevating turntable for up to 360 degree rotation and 70 degree elevation. The missiles are launched with the aid of four solid fuel rocket motors inside boosters attached to the outside of the massive missile. Once they have burned and the missile is aloft, it fires a liquid-fuelled ramjet sustainer engine. It reaches speeds of up to Mach 4 and has an effective range of 50 to 55 kilometres depending upon the version. It carries a 135 kilogram warhead. A Soviet very long range medium-to-high altitude surface-to-air missile (SAM) system designed to defend large areas from bomber attack or other strategic aircraft (such as the SR-71 'Blackbird'). [Desc] Each battalion has six single-rail missile launchers for the 10.72 metre long missiles as well as a number of radar systems. The missile range is 200 to 400 kilometres depending on the model. A Soviet mobile surface-to-air missile (SAM) system used in low level air defence system designed to protect ground forces from air attack. [Desc] Each battery consists of a number of similar tracked vehicles, one of which carries the 1S91 (NATO designation 'Straight Flush') 25 kilowatt G/H-band continuous-wave radar (range 75 kilometres) in addition to an optical sight and is usually accompanied by four triple-missile TELs and four trucks carrying three spare missiles and a crane. The missile range is 3 to 24 kilometres. A Soviet man-portable, shoulder-fired, low-altitude surface-to-air missile (SAM) system similar to the US Army REDEYE, with a high explosive warhead and passive infrared homing guidance.

A Soviet short-range, anti-aircraft amphibious-vehicle-mounted mobile surface-to-air missile (SAM) system based on the SA-N-4 and an all-in-one TELAR vehicle which can detect, track and engage aircraft independently or with the aid of regimental surveillance radars. [Desc] The Gecko carries four SA-8 missiles, and another 8 inside for reload purposes. The missile range is about 13 kilometres with a launch weight of 190 kilograms. The SA-8 missile uses infrared tracking to find its targets. A Soviet short-range, anti-aircraft amphibious-vehicle-mounted mobile surface-to-air missile (SAM) system consisting of the SA-9 launcher atop the BRDM-2A. [Desc] The Gaskin can carry two missiles boxes on the launch pad and four more inside for reload purposes. Missiles can be launched one at a time, two at a time, or four at a time. The Gaskin does not have radar. The missile range is 5 to 8 kilometres with a launch weight of 30 kilograms. A Russian surface-to-air missile (SAM) system similar to the US Patriot. [Desc] It was developed as a PVO long-range system to defend strategic targets against both conventional aircraft and cruise missiles, while the contemporary S-300V (NATO designation SA-12A Gladiator/SA-12B Giant) series was developed as a more mobile system to protect the ground forces from aircraft and short-range ballistic missiles. The S-300 missiles are sealed rounds and require no maintenance over their lifetime. The missile range is 50 to 200 kilometres depending on the model. A Russian medium-range, medium-altitude surface-to-air missile (SAM) system, the successor to the SA-6 'Gainful'. [Desc] It features improvements in number of missiles carried per TEL, range and altitude performance, missile speed, guidance accuracy and warhead potency. It is designed to engage maneuverable aircraft such as jets, helicopters and cruise missiles. The missile range is 3 to 50 kilometres depending on the model. A Russian long-range, high-altitude surface-to-air missile system designed primarily to intercept incoming ballistic missiles (counterpart to the SA-10 'Grumble'). [Desc] The system is very similar to the SA-10 in terms of configuration, but unlike the SA-10 there are two different sizes of missiles. The smaller 9M82 missiles, called SA-12B 'Gladiator' by NATO, are similar in size and range to those of the SA-10 system. However the 9M83 (SA-12A 'Giant') missiles are much larger and only two can be carried on each TELAR, rather than four. These vehicles, in combination with the command vehicle and 'Grill Pan' tracking radar, 'Bill Board A' surveillance radar and 'High Screen' ballistic missile detection radar, scan a specific area of the sky and engage aerial theats including ballistic missiles which are detected transiting it. The 'Gladiator' missiles have a maximum engagement range of around 75 kilometres while the 'Giant' missiles can engage targets out to 100 kilometres and up to altitudes of around 100,000 feet. In both cases the warhead is around 150 kilograms. A Russian highly mobile, visually aimed, optical/infra-red guided, low-altitude, short-range surface-to-air missile (SAM) system (successor of the SA-9 'Gaskin'). [Desc] Rather than being mounted on an amphibious but lightly armoured BRDM chassis like the SA-9, the SA-13 is mounted on a slightly better protected and more mobile tracked, modified MT-LB. Four missiles are mounted on the turret in boxes, ready to launch, and eight more are carried inside the vehicle as reloads. Top missile speed is around Mach 2, engagement range is 500 to 5000 metres and engagement altitude is up to 11,500 feet. It can also use the SA-9 'Gaskin', SA-7 'Grail', and SA-14 'Gremlin' missiles. A Russian low and medium-altitude, short-range surface-to-air missile (SAM) system designed for engaging aircraft, helicopters, cruise-missiles, precision munitions and remotely-piloted vehicles. [Desc] It is designed to protect targets from attack at all times and in any weather not only by shooting down attacking aircraft but also destroying any munitions before they reach the target. It is air-portable and equipped with NBC (nuclear, biological and chemical) protection. Each 9K331 vehicle is a completely autonomous TELAR although it can be linked into a greater air-defence system. The radar is a modern, phased-array type and eight missiles are stored vertically, ready to fire. The 9M330 missile is 3.5 metres long with a peak speed speed of around Mach 2.8. Guidance is via radio command and detonation via a radar proximity fuze. A Russian man-portable air defence missile system (MANPADS) was developed in the Soviet Union as a response to the poor performance of the earlier SA-7 'Grail' system. [Desc] The missile includes an all-new infra-red homing seeker head. The missile range is about 4,500 metres. A Russian man-portable air defence missile system (MANPADS), the successor to the SA-14 'Gremlin' system. [Desc] Uses infra-red homing. A Russian medium-range, medium-altitude surface-to-air missile (SAM) system, the successor to the SA-11 'Gadfly'. [Desc] Possibly the biggest change from the SA-11 'Gadfly' system is the fact that the 9S18M1 'Snow Drift' surveillance radar is mounted on the TELAR, making each launcher more independent and allowing more targets to be tracked in different locations at the same time. Range, altitude and target engagement have improved as well. Range is reported as being up to 50 kilometres, maximum altitude around 82,000 feet and maximum target speed around Mach 4. A Russian man-portable air defence missile system (MANPADS), the successor to the SA-16 'Gimlet' system. [Desc] Uses infra-red homing. A Soviet Integrated Air Defense System carrying six (2S6) or eight (2S6M/2S6M1) 9K111 missiles in two banks of two pairs, each pair being able to be elevated independently. [Desc] Effective engagement ranges are 2.4 to 8 kilometres and altitudes are up to 11,500 feet. Each missile is 3.2 metres long, weighs 65 kilograms with a warhead of 16 kilograms, flies at around Mach 3.5 and can engage targets flying at up to Mach 1.5. A missile designed to be launched from the ground to destroy aircraft. [Desc] It is a type of anti-aircraft system. For example, the US MIM-series and RIM-series, and the Soviet SA-series missiles. A surface-to-surface guided projectile launched from a hand-held, vehicle mounted, trailer mounted or fixed installation or from a ship. [Desc] Surface-to-surface missiles are usually guided (an unguided surface-to-surface missile is usually referred to as a rocket). They are often powered by a rocket motor or sometimes fired by an explosive charge, since the launching platform is typically stationary or moving slowly. They usually have fins and/or wings for lift and stability, although hyper-velocity or short-ranged missiles may utilise body lift or fly a ballistic trajectory.

[Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. NA [Desc] NA A fuel made from vegetable oils (for example: soybean or canola), animal fats, and/or recycled grease, and intended for use in diesel engines. [Desc] For U.S. Energy Information Administration reporting, biodiesel is a fuel composed of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats, and meeting the requirements of American Society for Testing and Materials (ASTM) D6751. Biodiesel is registered with the EPA as both a fuel and a fuel additive. Its designation as B100 indicates it is unblended (100 percent) biodiesel. It can serve as a substitute for petroleum-derived diesel or distillate fuel. Biodiesel Blend is a fuel that combines pure biodiesel stock with petroleum-based diesel. A fuel blended from biodiesel and petroleum-based diesel fuel, and intended for use in diesel engines. [Desc] Biodiesel Blend is designated BXX, where XX represents the volume percentage of biodiesel fuel in the blend. The blending ratio typically varies from 2 percent biodiesel (B2) up to 99.9 percent biodiesel (B99.9), with unblended biodiesel referred to as B100. Blending may occur at the point of biodiesel production, at an intermediate storage or distribution facility, or at the point-of-sale (for example: a motor vehicle station). Natural gas compressed into high-pressure cylinders and used as an environmentally friendly fuel. [Desc] Natural gas occurs naturally underground, consisting chiefly of methane and is often found associated with petroleum. A petroleum fraction used as fuel in diesel engines. [Desc] NA A mixed biofuel consisting of 85 percent ethanol and 15 percent unleaded gasoline, commonly known as 'E85'. [Desc] It can be used to run automobiles known as flexible fuel vehicles (FFV). Using E85 in non-FFV vehicles can cause corrosion of vehicle parts, because these parts are notá incompatible with high concentrations of ethanol. A colorless odorless highly flammable diatomic gas that may be used as an alternative fuel for transportation. [Desc] Using a fuel cell, hydrogen may be used to generate electricity to power electrically-driven wheels, or it may be directly combusted. Hythane (Hydrogen Compressed Natural Gas (HCNG)) is a mixture of natural gas (methane) and hydrogen. [Desc] Hythane is usually 5-7 percent hydrogen by energy. A petroleum distillate containing liquid hydrocarbons which boils in the range 150 to 300 degrees Centigrade. [Desc] It is used as a fuel for tractors and jet engines, and in domestic heaters. Natural gas that has been liquefied for ease of transport by cooling the gas to -162 degrees Centigrade. [Desc] It is stored in a vacuum bottle-type container at very low temperatures and under moderate pressure. Natural gas has 600 times the volume of LNG. A mixture of propane and butane, usually with propylene and butylenes present in small concentration and a powerful odorant, ethyl mercaptan, added so that leaks can be detected easily. [Desc] It becomes liquid at room temperature at 6 bar pressure, so it is supplied in pressurised steel bottles. The liquefied gas has an expansion ratio of about 250:1. Used as a fuel in heating appliances and vehicles. LPG is manufactured during the refining of crude oil, or extracted from oil or gas streams as they emerge from the ground. A colorless gas, C3H8, derived from natural gas and petroleum and widely used as a fuel. [Desc] Commonly transported and dispensed in liquefied form, especially in pressurized hand-carry tanks for use as a fuel for outdoor cooking in barbecues and portable stoves. The standard steel container holds 18 litre (4.73 U.S. gallon) and is often termed a 'barbecue tank'. Due to its low boiling point, liquefied propane vaporizes as soon as it is released from its pressurized container. Note that Liquefied Petroleum Gas (LPG) sold as an automotive fuel is a combination of propane and butane, often with propylene and/or butylenes, plus an odorant. Refined petroleum as used as a fuel in motor vehicles.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

If the feature is circular, 360 degrees is recorded. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

Thus, any particular hue can be designated by a number and a letter such as 5R or 10YR. Any single vertical section through the neutral gray axis and a particular hue constitutes a colour chart on which the colors grade in value from light at the top to dark at the bottom, and in chroma (degree of saturation) from gray at one edge to the most vivid colors out at the margin. Both value and chroma are numbered so any particular colour can be given a numerical designation representing hue, value, and chroma such as 5R 6/4 and 10YR 8/2.

The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

An assembly of valves, spools, pressure gauges and chokes fitted to the wellhead of a completed well to control production. [Desc] The christmas tree also incorporates facilities to enable safe access for well intervention operations such as slickline, electric wireline or coiled tubing. Its function is to both prevent the release of petroleum or gas from a well into the environment and also to direct and control the flow of formation fluids from the well. When the well is ready to produce petroleum or natural gas, valves are opened and the release of the formation fluids is allowed through a pipeline leading (eventually) to a refinery. An arrangement of piping or valves designed to control, distribute and often monitor fluid flow. [Desc] For smaller subsea fields, for example, the wellhead and christmas tree are installed directly on the seabed, with production from several wells co-mingled at a subsea manifold. Subsea manifolds are often linked by pipelines and umbilical control lines back to a nearby platform, where engineers can control and monitor the petroleum and natural gas production. A subsea structure covering the equipment (for example: a wellhead or a manifold) in order to protect against trawl gear damage.

An artificial-lift pumping system using a surface power source to drive a downhole pump assembly. [Desc] A beam and crank assembly creates reciprocating motion in a sucker-rod string that connects to the downhole pump assembly. The pump contains a plunger and valve assembly to convert the reciprocating motion to vertical fluid movement. A cylindrical or spherical vessel used to separate petroleum, natural gas and water from the total fluid stream produced by a well. [Desc] Gravity segregation is the main force that accomplishes the separation, thus the heaviest fluid settles to the bottom and the lightest fluid rises to the top. The objective is to maximize the hydrocarbon liquid recovery and to provide maximum stabilization to the resultant phases (liquid and gas) leaving the final separator. A tank in which the petroleum is stored after treatment (for example: to remove water). [Desc] NA A vessel used to treat oil-water emulsions so that the oil can be accepted by the pipeline or transport. [Desc] Treater mechanisms break down the emulsion using either heat, gravity segregation, chemical additives and/or electric current. The assembly of fittings, valves, and controls located at the surface and connected to the flow lines, tubing, and casing of the well so as to control the flow from the reservoir.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

[Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

[Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River').

[Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River').

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

[Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB).

[Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the accuracy of the vertical position of a feature, as a category. [Desc] NA The method by which the absolute horizontal accuracy was derived. [Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8. The primary type(s) of material composing a feature, exclusive of the surface.

[Desc] NA The area within the delineation of the feature. [Desc] NA The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument).

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

[Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart.

The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

[Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

[Desc] NA The distance measured from ground or water level (uphill/upstream side of the feature) to the deepest point of the feature. [Desc] May be used to measure the depth of an inland waterbody (for example: a lake), the depth of a terrain surface depression or excavation (for example: a crevice or trench), the distance to the deepest point of a drilled feature (for example: a water well or borehole) or the distance to the deepest point of a feature located entirely underground (for example: a cave chamber). In the case of a feature located below a waterbody (for example: a non-water well) the reference surface is the waterbody bottom, rather than the waterbody surface. The status of operation of a man-made structure, as a whole. [Desc] Includes actual operations, operational capability, and planned or proposed man-made structures. The physical condition of a man-made structure, as a whole, including the inside and/or outside of the structure and any contained and/or associated equipment.

[Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language.

[Desc] For example, an aqueduct carried across a valley by one or more bridge spans. The slope (rate of upward inclination of the surface from the horizontal) of the surface of a feature (for example: the terrain or a waterbody floor). [Desc] The (percent) slope is determined as the change in height divided by the horizontal distance over which the change takes place, multiplied by one hundred: ((h2-h1)/d)*100. Generally the slope is determined along the primary alignment of a feature (its established direction of flow or use; for example: a road, a railway, a ridge line, and/or a bridge). In those cases where the primary alignment is essentially horizontal (for example, a beach, a watercourse bank, or a cut) the surface slope is typically determined at right angles to the primary alignment.

The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8. The status of operation of a man-made structure, as a whole.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

Straightforward rapids with wide, clear channels which are evident without scouting. [Desc] Occasional maneuvering may be required, but stones and medium sized water waves are easily missed by trained paddlers. Swimmers are seldom injured and group assistance, while helpful, is seldom needed. Rapids that are at the upper end of this difficulty range are designated 'Class II+'. Rapids with moderate, irregular water waves which may be difficult to avoid and which can swamp an open canoe; strong eddies and powerful current effects can be found, particularly on large-volume rivers.

Intense, powerful but predictable rapids requiring precise boat handling in turbulent water; depending on the character of the river, it may include large, unavoidable water waves and holes or constricted passages demanding fast maneuvers under pressure. [Desc] A fast, reliable eddy turn may be needed to initiate maneuvers, scout rapids, or rest. Rapids may require 'must' moves above dangerous hazards. Scouting may be necessary the first time down. Risk of injury to swimmers is moderate to high, and water conditions may make self-rescue difficult. Group assistance for rescue is often essential but requires practiced skills. A strong Eskimo roll is highly recommended. Rapids that are at the lower or upper end of this difficulty range are designated 'Class IV-' or 'Class IV+' respectively. Extremely long, obstructed, or very violent rapids which expose a paddler to added risk; drops may contain large, unavoidable water waves and holes or steep, congested chutes with complex, demanding routes.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB).

[Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

[Desc] May be used when delineating separate parts of a single feature. For example, a single road may be delineated as several distinct parts since each part has a unique local name as it passes through different municipalities. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River').

[Desc] Includes actual operations, operational capability, and planned or proposed man-made structures. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself.

[Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

[Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

[Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions.

Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

[Desc] NA The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself.

[Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. The wall of the excavation within a quarry or extraction mine. [Desc] NA A 1-dimensional geometric primitive, representing the continuous image of a line. [Desc] Its subtypes include (but are not limited to): GM_LineString, GM_LineSegment, GM_GeodesicString, GM_Geodesic, GM_ArcString, and GM_Arc. The area within the delineation of the feature. [Desc] NA The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the accuracy of the vertical position of a feature, as a category. [Desc] NA The method by which the absolute horizontal accuracy was derived. [Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the horizontal accuracy of the geographic position of a feature, as a category. [Desc] NA A narrative or other textual description that records a general assessment of the quality of a resource (for example: a data instance, a data set or a data processing activity). [Desc] The quality of a data resource is dependent on the data providers knowledge regarding the lineage of the data and the processes that have been used to transform that data. No restriction is placed on the length of the statement. An indication that the delineation (for example: limits and information) of a feature is known. [Desc] NA A general evaluation of the quality of a feature assessment, as a category. [Desc] NA A general evaluation of the coverage quality of a survey, as a category. [Desc] See possibly accompanying Attribute: 'Position Quality Category' for additional survey-related information. One or more intended attribute domain values for one or more enumeration or codelist attributes that are not currently valid members of their respective attribute ranges. [Desc] The actual attribute domain values may have been previously, or may become in the future, valid members of the attribute domain range. The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8. The distance measured from ground or water level (uphill/upstream side of the feature) to the deepest point of the feature. [Desc] May be used to measure the depth of an inland waterbody (for example: a lake), the depth of a terrain surface depression or excavation (for example: a crevice or trench), the distance to the deepest point of a drilled feature (for example: a water well or borehole) or the distance to the deepest point of a feature located entirely underground (for example: a cave chamber). In the case of a feature located below a waterbody (for example: a non-water well) the reference surface is the waterbody bottom, rather than the waterbody surface. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself. The predominant height (the height of at least 50 percent) of the feature measured from the lowest point of the base at ground or water level (downhill side/downstream side). [Desc] NA The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart.

The order of the parts may vary with the generic part appearing at the beginning, middle or end. The type of a geographic name based on its scope of use, quality of source and/or its transliteration status. [Desc] NA The character set used for the display of characters with diacritics and special characters in a geographic name. [Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

[Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

[Desc] Includes actual operations, operational capability, and planned or proposed man-made structures. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself.

[Desc] The (percent) slope is determined as the change in height divided by the horizontal distance over which the change takes place, multiplied by one hundred: ((h2-h1)/d)*100. Generally the slope is determined along the primary alignment of a feature (its established direction of flow or use; for example: a road, a railway, a ridge line, and/or a bridge). In those cases where the primary alignment is essentially horizontal (for example, a beach, a watercourse bank, or a cut) the surface slope is typically determined at right angles to the primary alignment.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

The slope (rate of upward inclination of the surface from the horizontal) of the surface of a feature (for example: the terrain or a waterbody floor). [Desc] The (percent) slope is determined as the change in height divided by the horizontal distance over which the change takes place, multiplied by one hundred: ((h2-h1)/d)*100. Generally the slope is determined along the primary alignment of a feature (its established direction of flow or use; for example: a road, a railway, a ridge line, and/or a bridge). In those cases where the primary alignment is essentially horizontal (for example, a beach, a watercourse bank, or a cut) the surface slope is typically determined at right angles to the primary alignment.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB).

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River').

When opened they allow water to flow under or beside the gate. Commonly sluice gates will be installed perpendicular to the orientation of the flow of water within a watercourse and will be constructed as wide as the watercourse they regulate. Sluice gates may also be installed along the margins of watercourses for the purpose of controlling or permitting the flow of water to or from that watercourse into adjacent watercourses. Sluice gates may be used to regulate both tidal or non-tidal waters. A 0-dimensional geometric primitive, representing a position. [Desc] NA The area within the delineation of the feature.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB).

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply.

The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language.

[Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Name Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A field and/or stage partly or completely surrounded by a structure designed to allow spectators to stand or sit while viewing an event. [Desc] The field and/or stage may be enclosed in a building or be outdoors. Stadiums are surrounded on most or all sides by tiered seating for spectators. Often designed in size and shape to accommodate specific sports (for example: baseball, football, basketball or ice hockey), theater or musical performances. A 0-dimensional geometric primitive, representing a position. [Desc] NA The area within the delineation of the feature. [Desc] NA The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the accuracy of the vertical position of a feature, as a category. [Desc] NA The method by which the absolute horizontal accuracy was derived. [Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the horizontal accuracy of the geographic position of a feature, as a category. [Desc] NA A narrative or other textual description that records a general assessment of the quality of a resource (for example: a data instance, a data set or a data processing activity).

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

[Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language. The unique named feature identifier element in the NGA Geographic Names Data Base (GNDB).

[Desc] Its subtypes include (but are not limited to): GM_LineString, GM_LineSegment, GM_GeodesicString, GM_Geodesic, GM_ArcString, and GM_Arc. The area within the delineation of the feature. [Desc] NA The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument).

[Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived.

[Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the horizontal accuracy of the geographic position of a feature, as a category. [Desc] NA A narrative or other textual description that records a general assessment of the quality of a resource (for example: a data instance, a data set or a data processing activity).

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8.

[Desc] NA The slope (rate of upward inclination of the surface from the horizontal) of the surface of a feature (for example: the terrain or a waterbody floor). [Desc] The (percent) slope is determined as the change in height divided by the horizontal distance over which the change takes place, multiplied by one hundred: ((h2-h1)/d)*100. Generally the slope is determined along the primary alignment of a feature (its established direction of flow or use; for example: a road, a railway, a ridge line, and/or a bridge). In those cases where the primary alignment is essentially horizontal (for example, a beach, a watercourse bank, or a cut) the surface slope is typically determined at right angles to the primary alignment.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

[Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

[Desc] Vegetation reduces trafficability by requiring that either it must be 'overridden' (for example: scrub by a battle tank) or bypassed (for example: orchard trees by an infantryman). A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

[Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

[Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature. Some countries have more than one official language and therefore may have an official name for a feature in each official language.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability.

[Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions.

[Desc] NA An indication that horizontal clearance for vehicles on a land transportation route is restricted. [Desc] Horizontal clearance affects the maximum width of loads that extend laterally beyond the wheels of a vehicle. The type of a route width constriction based on the nature of the surrounding area. [Desc] For example, reduction in road width to less than 4 metres is considered to be a constriction. Width restrictions cause vehicles and people to travel through narrow passages creating choke points. The type of a route width expansion based on the nature of the expansion and/or surrounding area. [Desc] NA The minimum width of the travelled way of a route. [Desc] Excludes pavements and shoulders. The total usable width of the travelled way of a route. [Desc] Includes pavements and shoulders.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The distance available to pass a load that extends laterally beyond the wheels of a vehicle. [Desc] NA The least distance between the travelled way and any obstruction vertically above it. [Desc] Reference STANAG 2253. An indication that a feature is permanent. [Desc] Temporary features last, or are meant to last, for a limited time only. The physical condition of a man-made structure, as a whole, including the inside and/or outside of the structure and any contained and/or associated equipment.

The order of the parts may vary with the generic part appearing at the beginning, middle or end. The type of a geographic name based on its scope of use, quality of source and/or its transliteration status. [Desc] NA The character set used for the display of characters with diacritics and special characters in a geographic name. [Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the accuracy of the vertical position of a feature, as a category. [Desc] NA The method by which the absolute horizontal accuracy was derived. [Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8. The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The predominant species of a tract of vegetation. [Desc] NA The average diameter of tree crowns within a defined area. [Desc] The tree crown displays the leaves to allow capture of radiant energy for photosynthesis. Its diameter is usually measured by projecting the edges of the crown to the ground and measuring the length along one axis from edge to edge through the crown centre. Unless the crown has a regular shape, the width measured will depend on the axis selected for measurement. Two orthogonal axes are normally selected and averaged (for example: the maximum axis and the axis at 90 degrees to it); the two measurements are then averaged using an arithmetic mean (most common) or a geometric mean (for highly elliptical boles). The predominant foliage type of the vegetation. [Desc] NA The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL).

The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof.

(2) So seriously affected by adverse conditions that the road may remain closed for long periods. (3) Improvement of such a road can only be achieved by construction or realignment. Suitable for use in all weather conditions, however may have some reductions in usability due to weather. [Desc] For example, in the case of a road the following characteristics might apply: (1) With reasonable maintenance, passable throughout the year but at times the volume of traffic is considerably less than maximum capacity. (2) Normally not having a waterproof surface and considerably affected by rain, frost, thaw, or heat. (3) Closed for short periods of up to one day at a time by adverse weather conditions during which heavy use of the road would probably lead to collapse. Suitable for use under winter season conditions only. [Desc] For example, in the case of a road it may cross a waterbody and therefore is nonoperational until a sufficiently thick layer of ice has formed.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

[Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures.

Shelters may be equipped with disaster supplies and equipment such as food and cots. The distance measured from ground or water level (uphill/upstream side of the feature) to the highest point of a feature located completely underground. [Desc] For example, in the case of an underground dwelling the least depth below surface level would be measured to its ceiling. The least depth below surface level may be located at ground or water level and therefore have a value of zero (for example: an opencast extraction mine, a terrain depression or a lake). For depths defined with respect to a time-varying water level, consideration should be given to the use of Attribute: 'Hydrographic Depth'. The branch of the armed forces of a nation.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

[Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself.

[Desc] NA The slope (rate of upward inclination of the surface from the horizontal) of the surface of a feature (for example: the terrain or a waterbody floor). [Desc] The (percent) slope is determined as the change in height divided by the horizontal distance over which the change takes place, multiplied by one hundred: ((h2-h1)/d)*100. Generally the slope is determined along the primary alignment of a feature (its established direction of flow or use; for example: a road, a railway, a ridge line, and/or a bridge). In those cases where the primary alignment is essentially horizontal (for example, a beach, a watercourse bank, or a cut) the surface slope is typically determined at right angles to the primary alignment.

A hill or mountain situated over an opening or openings in the Earth's crust through which lava, cinders, steam, and/or gases, are or have been expelled. [Desc] NA A 0-dimensional geometric primitive, representing a position. [Desc] NA The area within the delineation of the feature. [Desc] NA The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The vertical distance from a specified vertical datum to the terrain surface of or at the base of the feature. [Desc] If the feature is not supported above the surface by another feature then the base of the feature is usually located at ground or water level on the downhill/downstream side. For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter. The method by which the absolute vertical accuracy was derived. [Desc] NA The difference between the recorded elevation of a feature and its true elevation referenced to the same vertical datum expressed as a linear error at 90 percent probability. [Desc] It may also be applied to a data set. If the data contains multiple accuracies, usually the worst accuracy which applies to 10% or more of the data is recorded. A general evaluation of the accuracy of the vertical position of a feature, as a category. [Desc] NA The method by which the absolute horizontal accuracy was derived. [Desc] NA The difference between the recorded horizontal coordinates of a feature and its true position referenced to the same geodetic datum expressed as a circular error at 90 percent probability.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control. [Desc] UUIDs are defined in ITU-T Rec. X.667 |||||||||||||||||||||||||||||||| ISO/IEC 9834-8. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL).

The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB).

A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name.

The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

[Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof. The physical condition of a man-made structure, as a whole, including the inside and/or outside of the structure and any contained and/or associated equipment. [Desc] The physical condition applies to any phase of the life cycle of a man-made structure from construction to destruction.

A narrative or other textual description of the screening, casing, and/or finishing of a water well. [Desc] A well screen is system of mesh screening or holes designed to allow water to enter a well or borehole without undue loss of flow while excluding sand, silt, and other geologic material. A well casing is a tubular structure placed in the drilled hole to maintain the physical opening from the underground water source to the surface, and also to insulate the passage of water from either loss or pollution in the intervening strata. The casing extends above the surface and protects against surface contaminants entering the water supply by its height and some form of covering.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name.

The type of a geographic name based on its scope of use, quality of source and/or its transliteration status. [Desc] NA The character set used for the display of characters with diacritics and special characters in a geographic name. [Desc] Individual character sets include diacritics and special characters from multiple languages in the same geographic region. The International Organization for Standardization (ISO 15924) four character code that designates a script. [Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB).

In the case of a survey marker (monument) this is usually the elevation assigned to the marker (monument). The dimension of a feature taken along its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line, a river, a rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the length is the distance between the bridge abutments along the bridge centreline. In the case of a dam, the length is the distance along the dam crest. If no established direction of flow or use exists then (1) if the feature is irregular in shape its length is its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the longer axis; for a round feature, the diameter. The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane. [Desc] The primary alignment of a feature is its established direction of flow or use (for example: a road, a power line right-of-way, a river, rapid, and/or a bridge). A feature-specific rule may apply. In the case of a bridge, the width is the distance perpendicular to the bridge centre-line and generally in the horizontal plane. In the case of a dam, the width is the distance perpendicular to (across the) the dam crest. If no such direction of flow or use exists then (1) if the feature is irregular in shape its width is taken perpendicular to the direction of its greatest horizontal dimension (see Attribute: 'Greatest Horizontal Extent'), else (2) if the feature is regular in shape then a shape-specific rule may apply: for a rectangular feature, the length of the shorter axis; for a round feature, the diameter.

The globally unique and persistent identifier of an entity (for example: feature or event) instance as specified by a Uniform Resource Name (URN) in accordance with the Internet Engineering Task Force (IETF) RFC2396 and RFC2141. [Desc] It is based on the Uniform Resource Identifier (URI), a compact string of characters for identifying an abstract or physical resource. The term 'Uniform Resource Name' (URN) refers to the subset of URI that are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable. The URN is drawn from one of a set of defined namespaces, each of which has its own set name structure and assignment procedures. The Universal Unique Identifier (UUID) that is assigned to a feature in order to uniquely identify it for the purpose of maintaining relationships between features (relational database) and version control.

[Desc] NA The distance measured from ground or water level (uphill/upstream side of the feature) to the deepest point of the feature. [Desc] May be used to measure the depth of an inland waterbody (for example: a lake), the depth of a terrain surface depression or excavation (for example: a crevice or trench), the distance to the deepest point of a drilled feature (for example: a water well or borehole) or the distance to the deepest point of a feature located entirely underground (for example: a cave chamber). In the case of a feature located below a waterbody (for example: a non-water well) the reference surface is the waterbody bottom, rather than the waterbody surface. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL). Note that the feature may be supported above the surface by another feature (for example: a tower supported by a building) and as a consequence the value of the Height Above Surface Level is different (larger) than the base-to-top height of the feature (for example: supported tower) itself. The vertical distance measured from the lowest point of the base of the feature at ground or water level (downhill/downstream side) to the tallest point of the feature. [Desc] For non-inland water bodies, the water level is usually understood to be Mean Sea Level (MSL).

The elevation from a specified vertical datum to the highest point on a feature. [Desc] In the case of multiple features that may be stacked on each other (for example: a railway on a bridge, a superstructure on a building, or an aerial on a tower) the highest elevation is that of the entire feature stack. For example, the highest elevation of a church is that of its steeple and not that of the roof of the church itself. The church itself may have a height above surface level that excludes the additional height of the steeple superstructure located on the church roof.

[Desc] A script is a set of graphic characters used for the written form of one or more languages. The International Organization for Standardization (ISO 639-3) three character code that designates the language or macrolanguage of the source of a geographic name. [Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB). [Desc] Typically used together with Attribute: 'Named Feature Identifier' to provide a unique index into the NGA Geographic Names Data Base (GNDB) from which NGA draws all of its feature name information. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart except that any diacritics and special characters have been replaced with their corresponding Roman characters. [Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'.

[Desc] It is generally considered to consist of a specific part, a generic part, and any articles or prepositions. The order of the parts may vary with the generic part appearing at the beginning, middle or end. A complete name that is used to designate the entity as that designation would normally be written by the originating culture on a map or chart, except that its components have been arranged into an order that facilitates alphabetic ordering and search. [Desc] The component order is such that the specific part of the name appears first, followed by an optional comma, the generic part of the name, and then finally any articles or prepositions (for example: 'Everest, Mount' or 'Mexico, Gulf of'). For some geographic names no reordering of the full name is required (for example: 'Tigrus River'). Geographic names that are believed to no longer exist are enclosed in double parenthesis, as: '(( Name ))'. The designation of the type of a feature with which a geographic name is associated, as used in the NGA Geographic Names Data Base (GNDB). [Desc] A designated feature type also has a (unique, single) geographic name classification. An indication that a feature has more than one official, native script, geographic name. [Desc] Multiple official names may exist when a feature passes through more than one country and those multiple countries have different official names for that feature.

[Desc] A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish. The International Organization for Standardization (ISO 639-3) three character code that designates the language dialect, if applicable, of the source of a geographic name. [Desc] Some languages have no (child) dialects. Each language dialect is unique to only one parent language. The unique name identifier element in the NGA Geographic Names Data Base (GNDB).

[Desc] NA NA [Desc] NA A continuous surface over dry land and non-tidal waters (for example: lakes). [Desc] In the case of non-tidal waters it is necessary to specify hydrologic conditions in order to ensure a precise reference surface specification. Over extensive areas it is often defined by a digital elevation model (for example: a matrix of elevation values or a Triangulated Irregular Network (TIN)). Over tidal waters (for example: oceans) it is usually considered to be extended to cover the remainder of the world based on a Mean Sea Level (MSL) surface. A continuous surface over the oceans (or its hypothetical extension under the land masses) defined by the mean of sea level surfaces approximated and observed over 19 years. [Desc] NA A fixed reference for elevations derived from a general adjustment in 1929 of the first-order leveling nets of both the United States and Canada. [Desc] In the adjustment, mean sea level was held fixed as observed at 21 tide stations in the United States and 5 in Canada. A fixed reference for elevations derived from a general adjustment of the first-order terrestrial levelling nets of the United States, Canada, and Mexico. [Desc] In the adjustment, only the height of the primary tidal bench mark, referenced to the International Great Lakes Datum of 1985 local mean sea level height value, at Pointe-au-Pere, Quebec, on the Gulf of St. Lawrence was held fixed, thus providing minimum constraint.
