Geometry

A description of a spatial location in the real world according to a defined reference system.

NOTE: A Geometry can be complex, such as a jurisdictional area that consists of multiple islands.

Specializations of Geometry

Class	Description
Area By Circle	An area geometry encoded as a circle.
Area By Code	An area geometry whose extent is not modelled here but can be resolved using :hasLookupCode and an external location referencing system.
Area By Code	An area geometry whose extent is not modelled here but can be resolved using :hasLookupCode and an external location referencing system.
Area By Grid	An area geometry encoded as a grid. The rectangle defined by lower-left and upper-right is the base cell, which is replicated eastward (columns) and northward (rows).
Area By Grid	An area geometry encoded as a grid. The rectangle defined by lower-left and upper-right is the base cell, which is replicated eastward (columns) and northward (rows).
