Engineering survey, topographic mapping.
State law defines system in US survey feet. Federal definition is metric - see code 2864. Replaces NAD83 / SPCS for applications with an accuracy of better than 3 feet. Replaced by NAD83(NSRS2007) / SPCS.
United States (USA) - Wyoming - counties of Fremont; Hot Springs; Park; Sweetwater.
Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: ftUS.
