Kan. Stat. § 58-20a09
The Kansas coordinate systems of 1983 and 1927 were established for defining and stating the geographic positions or locations of points on the surface of the earth within the state of Kansas. The 1983 system is based on the geodetic reference system 1980 ellipsoid of the North American datum of 1983 and was adopted in K.S.A. 58-20a06, prior to its repeal. The 1927 system is based on the Clarke 1866 ellipsoid of the North American datum of 1927 and was not adopted in Kansas statute but was widely used in Kansas prior to adoption of the 1983 system. Both systems are divided into a north zone and a south zone. The area north of the south line of the following counties constitutes the north zone: Wallace, Logan, Gove, Trego, Ellis, Russell, Ellsworth, Saline, Dickinson, Morris, Wabaunsee, Shawnee, Douglas and Johnson. The area south of the north line of the following counties constitutes the south zone: Greeley, Wichita, Scott, Lane, Ness, Rush, Barton, Rice, McPherson, Marion, Chase, Lyon, Osage, Franklin and Miami. The plane coordinate values of a point on the earth's surface, to be used to express the geographic position or location of such point in the appropriate zone of the Kansas coordinate systems of 1983 and 1927, consist of two distances, expressed in feet and decimals of a foot or meters and decimals of a meter. If the values are expressed in feet, a definition of one foot equals 1200/3937 meter exactly shall be used as the standard foot for the Kansas coordinate systems of 1983 and 1927. One of the distances, known as the "Northing" or "N" for the 1983 system, or "y" for the 1927 system, gives the position in a north and south direction. The other distance, known as the "Easting" or "E" for the 1983 system, or "x" for the 1927 system, gives the position in an east and west direction. For purposes of more precisely defining the Kansas coordinate systems of 1983 and 1927, the following definitions shall apply:
