Title:
AQ059_P
|
Definition:
A section of a transportation route where its size (for example: narrowing or expansion
in width) and/or operating speed is significantly different than in the adjacent sections
of the route.
|
Description:
For example, an increase or decrease in the number of lanes in a road. Constrictions
along or beside a transportation route may impede the flow of vehicles or people thus
resulting in 'choke points'.

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).

GEM-zI007.LZN-singleValue
|
Definition:
|
The dimension of a feature taken along 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, 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.

|
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:
|
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:
|
The International Organization for Standardization (ISO 639-3) three character code
that designates the language or macrolanguage of the source of a geographic name.
|
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.

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.

UFI
|
Definition:
|
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.
|
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
