43-22-6. Definition of systems. For purposes of more precisely defining the South Dakota coordinate systems of 1927 and 1983, the following definition by the United States Department of Commerce, National Oceanic and Atmospheric Administration, is adopted:

(1) The South Dakota coordinate system of 1927, north zone, is a Lambert conformal projection of the Clarke Spheroid of 1866, having standard parallels at north latitudes 44 degrees 25 minutes and 45 degrees 41 minutes, along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 100 degrees 00 minutes west of Greenwich and the parallel of 43 degrees 50 minutes north latitude. This origin is given the coordinates: x equals 2,000,000 feet and y equals 0 feet.

(2) The South Dakota coordinate system of 1927, south zone, is a Lambert conformal projection of the Clarke Spheroid of 1866, having standard parallels at north latitudes 42 degrees 50 minutes and 44 degrees 24 minutes, along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 100 degrees 20 minutes west of Greenwich and the parallel 42 degrees 20 minutes north latitude. This origin is given the coordinates: x equals 2,000,000 feet and y equals 0 feet.

(3) The South Dakota coordinate system of 1983, north zone, is a Lambert conformal conic projection of the North American Datum of 1983, having standard parallels at north latitudes 44 degrees 25 minutes and 45 degrees 41 minutes along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 100 degrees 00 minutes west of Greenwich and the parallel 43 degrees 50 minutes north latitude. This origin is given the coordinates: x equals 600,000 meters and y equals 0 meters.

(4) The South Dakota coordinate system of 1983, south zone is a Lambert conformal conic projection of the North American Datum of 1983, having standard parallels at north latitudes 42 degrees 50 minutes and 44 degrees 24 minutes along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 100 degrees 20 minutes west of Greenwich and the parallel 42 degrees 20 minutes north latitude. This origin is given the coordinates: x equals 600,000 meters and y equals 0 meters.Source: SL 1947, ch 231, § 5; SDC Supp 1960, § 18.0305 (1); SL 1988, ch 349, § 4.
