Geometry
Class Description
A Geometry represents a shape. Various types (subclasses) of Geometry are defined in the GeoSPARQL ontology including the classes: Point, Polygon, and Curve.Core properties are: o asWKT: specifies the well-known text (WKT) encoding of a given geometry. The default reference system for the coordinate values is assumed to be WGS84. GeoSPARQL supports the identification of alternate reference systems, captured as IRIs and concatenated with the coordinates. In addition, the pattern specifies the following generic properties to support the reference of locations by other classes: • hasLocation: captures the relationship between objects and the spatial locations they occupy • associatedLocation: introduced to capture the association of some object with a particular location. For example, a train station may occupy a fairly large spatial location but be associated with a particular point.
