Detailed Description

Represents a Projected Coordinate System (PCS).

To obtain a valid PCS, the instance must be initialized either with one of the import functions (e.g. ProjectedCoordinateSystemInterface::importFromWTK) or via one of ProjectedCoordinateSystemDB lookup methods (e.g. ProjectedCoordinateSystemDB::searchByEPSG)
