A GML serialization of a geometry object.
The class spatial-object represents everything that can have a spatial representation. It is superclass of feature and geometry.
SpatialObject
The class represents the top-level geometry type. This class is equivalent to the UML class GM_Object defined in ISO 19107, and it is superclass of all geometry types.
Geometry
Feature
This class represents the top-level feature type. This class is equivalent to GFI_Feature defined in ISO 19156:2011, and it is superclass of all feature types.
The default geometry to be used in spatial calculations. It is Usually the most detailed geometry.

inside
The number of measurements or axes needed to describe the spatial position of this geometry in a coordinate system.
spatialDimension
(true) if this geometric object is the empty Geometry. If true, then this geometric object represents the empty point set for the coordinate space.
isEmpty
coordinateDimension
The number of measurements or axes needed to describe the position of this geometry in a coordinate system.
asWKT
The WKT serialization of a geometry
The GML serialization of a geometry
asGML
isSimple
(true) if this geometric object has no anomalous geometric points, such as self intersection or self tangency.
dimension
The topological dimension of this geometric object, which must be less than or equal to the coordinate dimension. In non-homogeneous collections, this will return the largest topological dimension of the contained objects.
Connects a geometry object with its text-based serialization.
