GeoProjectionData

GeoProjectionData["projection", "property"]
gives the value of the specified property for the specified cartographic projection.

GeoProjectionData["projection"]
gives the complete options for the default form of the specified projection.

  • 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.
