Unit: metre
Geodetic CRS: NAD83
Datum: North American Datum 1983
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Revision date: 1995-06-02
Scope: Engineering survey, topographic mapping.
Remarks: State law defines system in US survey feet. See code 2233 for equivalent non-metric definition. For applications with an accuracy of better than 1m, replaced by NAD83(HARN) / SPCS.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
