- GeoProjectionData supports all projections used by the U.S. State Plane Coordinate Systems from 1927 to 1983.
- GeoProjectionData["SPCS27"] and GeoProjectionData["SPCS83"] give the names of all state plane zones.
- GeoProjectionData["UTMZone"] gives names for all UTM zones.
- For any state plane or UTM zone, GeoProjectionData["zone"] gives the name and the standard parameters of the projection used.
