Tennessee Code Title 66. Property § 66-6-103

(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.
