Engineering survey, topographic mapping.
State law defines system in US survey feet. See code 2885 for equivalent non-metric definition. Replaces NAD83 / SPCS for applications with an accuracy of better than 1m. Replaced by NAD83(NSRS2007) / SPCS.
Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
