Reference

geo:Geometry

Definition

A coherent set of direct positions in space. The positions are held within a Spatial Reference System (SRS).

Scope

Parent class(es): Spatial Object (http://www.opengis.net/ont/geosparql#SpatialObject).

CDIF

Definition

geosparql:Geometry - structured spatial geometry serialized as Well-Known Text (geosparql:asWKT) with an optional coordinate reference system (geosparql:crs). Modelled as a real class (intentional exception to the union-shorthand: the BB defines real structure here).

Inheritance

No generalization relationships.

Attributes

Name	Type	Multiplicity	Description
identifier	XsdAnyUri	[0..1]	Documentation Original Reference schema:identifier Definition The identifier property represents any kind of identifier for any kind of [[Thing]], such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See [background notes](/docs/datamodel.html#identifierBg) for more details. Scope Domain: Thing (https://schema.org/Thing). Range: PropertyValue (https://schema.org/PropertyValue), Text (https://schema.org/Text), URL (https://schema.org/URL). CDIF Definition The primary identifier for the dataset; other identifiers should be listed in the sameAs field. Schema.org has three ways of encoding identifiers-- a text description, a URL, or by using the schema:PropertyValue field. The Science on Schema.org guidance strongly recommends using the PropertyValue approach. see https://github.com/ESIPFed/science-on-schema.org .... Dataset.md#identifier. Ideally, for any given data provided they would provide identifiers either all as strings or all as identifier_type. Scope @id - resolvable URI for the geometry node.
asWKT	string	[0..1]	Documentation Original Reference geosparql:asWKT Definition The WKT serialization of a Geometry Scope Domain: Geometry (http://www.opengis.net/ont/geosparql#Geometry). Range: http://www.opengis.net/ont/geosparql#wktLiteral. CDIF Definition geosparql:asWKT - Well-Known Text serialization of the geometry.
crs	XsdAnyUri	[0..1]	Documentation Original Reference cdif:crs CDIF Definition geosparql:crs - coordinate reference system URI.
