Engineering survey, topographic mapping.
State law defines system in US survey feet. Federal definition is metric - see code 26974. For applications with an accuracy of better than 3 feet, replaced by NAD83(HARN) / SPCS.
Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: ftUS.
