- All Superinterfaces:
A Geographic CRS is not suitable for mapmaking on a planar surface, because it describes geometry on a curved surface. It is impossible to represent such geometry in a Euclidean plane without introducing distortions. The need to control these distortions has given rise to the development of the science of map projections.

- Departure from OGC/ISO abstract specification:
Departure for historical reasonThis interface is kept conformant with the specification published in 2003. The 2007 revision of ISO 19111 removed the
GeocentricCRStypes, handling both using the
GeodeticCRSparent type. GeoAPI keeps them since the distinction between those two types is in wide use.
