66-6-102. Coordinates used.

The plane coordinate values for a point on the earth's surface, used to express the geographic position or location of such point, shall consist of two (2) distances expressed in United States survey feet and decimals of a foot when using the Tennessee Coordinate System of 1927, and expressed in meters and decimals of a meter when using the Tennessee Coordinate System of 1983. Coordinate values may also be expressed in United States survey feet and decimals of a foot for the Tennessee Coordinate System of 1983 as specified in § 66-6-103(c). One (1) of these distances, to be known as the “x-coordinate,” shall give the position in an east-and-west direction; the other, to be known as the “y-coordinate,” shall give the position in a north-and-south direction. These coordinates shall be made to depend upon and conform to plane rectangular coordinate values for certain monumented points of the North American horizontal geodetic control network as published by the national ocean survey/national geodetic survey, formerly the United States coast and geodetic survey, or its successors, and whose plane coordinates have been computed on the systems defined in this chapter. Such monumented points of the North American horizontal geodetic control network shall be those existing or newly established in conformity with the standards of accuracy for first or second order geodetic surveying as prepared and published by the federal geodetic control committee (FGCC) of the United States department of commerce.
