Explain Interior, Boundary and Exterior
|Reported by:||mloskot||Owned by:||kneufeld|
For completeness, it would be good to give short description of these three fundamental terms in the PostGIS manual:
The IBM Informix manual provides short but clear definitions of Interior, Boundary, and Exterior:
All geometries occupy a position in space defined by their interior, boundary, and exterior. * The exterior of a geometry is all space not occupied by the geometry. * The boundary of a geometry serves as the interface between its interior and exterior. * The interior is the space occupied by the geometry.
PostGIS manual could include similar.
