§ 89-6-7. Definitions applicable to Mississippi Coordinate System of 1983

For purposes of more precisely defining the Mississippi Coordinate System of 1983, the following definition by the National Ocean Service/National Geodetic Survey is adopted:
The "Mississippi Coordinate System of 1983 East Zone" is a transverse Mercator projection of the North American Datum of 1983, having a central meridian of eighty-eight (88) degrees fifty (50) minutes west of Greenwich, on which meridian the scale is set at one (1) part in twenty thousand (20,000) too small. The origin of coordinates is at the intersection of the meridian eighty-eight (88) degrees fifty (50) minutes west of Greenwich and the parallel twenty-nine (29) degrees thirty (30) minutes north latitude. This origin is given the coordinates: N 0 meters and E 300,000 meters.
The "Mississippi Coordinate System of 1983 West Zone" is a transverse Mercator projection of the North American Datum of 1983, having a central meridian ninety (90) degrees twenty (20) minutes west of Greenwich, on which meridian the scale is set at one (1) part in twenty thousand (20,000) too small. The origin of coordinates is at the intersection of the meridian ninety (90) degrees twenty (20) minutes west of Greenwich and the parallel twenty-nine (29) degrees thirty (30) minutes north latitude. This origin is given the coordinates: N 0 meters and E 700,000 meters.
