§ 66-6-103 — Technical definitions of systems

(a) For purposes of more precisely defining the Tennessee Coordinate System of 1927, the following definition by the United States coast and geodetic survey, now the national ocean survey/national geodetic survey, is adopted: The "Tennessee Coordinate System of 1927" is a Lambert conformal conic projection of the Clarke spheroid of 1866, having standard parallels at north latitudes 35° 15' and 36° 25', along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 86° 00' west of Greenwich and the parallel 34° 40' north latitude. This origin is given the coordinates: x (easting) = two million feet (2,000,000') and y (northing) = one hundred thousand feet (100,000'). (b) For purposes of more precisely defining the Tennessee Coordinate System of 1983, the following definition by the national ocean survey/national geodetic survey is adopted: The "Tennessee Coordinate System of 1983" is Lambert conformal conic projection of the North American Datum of 1983, having standard parallels at north latitudes 35° 15' and 36° 25', along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 86° 00' west of Greenwich and the parallel 34° 20' north latitude. This origin is given the coordinates: x (easting) = six hundred thousand meters (600,000 m.) and y (northing) = zero meters (0 m.). (c) The definition of the "U.S. Survey Foot" is exactly 1,200/3,937 meters.
