The set of geometry types proposed by OGC's SQL with Geometry Types environment is based on the OpenGIS Geometry Model. In this model, each geometric object has the following general properties:
It is associated with a spatial reference system, which describes the coordinate space in which the object is defined.
It belongs to some geometry class.
