Definition:

The dimension of a feature taken perpendicular to its primary alignment of use and generally in the horizontal plane.

Description:

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.

Description:

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.

Definition:

The elevation from a specified vertical datum to the highest point on a feature.

Description:

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 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.

Description:

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.

Definition:

An indication that a feature has more than one official, native script, geographic name.

Description:

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.

leastDepthBelowSurfLevel

Title:

LEA

Definition:

The distance measured from ground or water level (uphill/upstream side of the feature) to the highest point of a feature located completely underground.

Description:

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'.

Description:

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.
