Uses NADCON method which expects longitudes positive west; EPSG GeogCRSs NAD83 (code 4269) and NAD83(HARN) (code 4152) have longitudes positive east. May be taken as approximate transformation NAD83-WGS 84 - see code 1746.

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.
