class RGeo::CoordSys::CS::CoordinateSystemFactory

A class implementing the CS_CoordinateSystemFactory interface. It provides methods for building up complex objects from simpler objects or values.

Note that the methods of CS_CoordinateSystemFactory do not provide facilities for setting the authority. If you need to set authority values, use the create methods for the object classes themselves.
