The State Plane Coordinate system divides the U.S. into a hundred or more distinct grid surfaces (Zones). Do not mix coordinates from one Zone with that in another. In you need to cross Zone boundaries, use Geodetic Positions. The utilities in this package provide methods for converting between Geodetic Positions and State Plane Coordinates or for finding an SPC Zone.
This utility uses NGS program SPCS83 or program GPPCGP to convert NAD83 or NAD27 Geodetic Positions to State Plane Coordinates (SPC)
- Latitude/Longitude -> SPC
- SPC -> Latitude/Longitude
- Find Zone
