Topographic mapping (small scale).
KS DOT defines system in US survey feet. See code 6922 for equivalent metric definition. For applications with an accuracy of better than 5ft, use NAD83(2011) / LCC (ftUS) (CRS code 6924).
Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: ftUS.
