Revision date: 2001-11-06
Scope: Engineering survey, topographic mapping.
Remarks: State law defines system in US survey feet. Federal definition is metric - see code 26943. For applications with an accuracy of better than 3 feet, replaced by NAD83(HARN) / SPCS.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: ftUS.
