§ 102‑1.1.  Name anddescription in relation to 1983 North American Datum.

From and after the date andtime the North Carolina Geodetic Survey Section in the Division of LandResources of the Department of Environment and Natural Resources receives fromthe National Geodetic Survey, official notice of a complete, publisheddefinition of the North American Datum of 1983 including the State planecoordinate constants applicable to North Carolina, the official survey base forNorth Carolina shall be a system of plane coordinates to be known as the"North Carolina Coordinate System of 1983," said system being definedas a Lambert conformal projection of the "Geodetic Reference System (GRS80 Ellipsoid)" having a central meridian of 79° – 00' west from Greenwich andstandard parallels of latitude of 34° – 20' and 36° – 10' north of the equator,along which parallels the scale shall be exact. All coordinates of the systemare expressed in metres, the x coordinate being measured easterly along thegrid and the y coordinate being measured northerly along the grid. The U.S.Survey Foot, 1 meter = 39.37 inches or 3.2808333333 feet, shall be used as aconversion factor. The origin of the coordinates is hereby established on themeridian 79° – 00' west from Greenwich at the intersection of the parallels 33°– 45' north latitude, such origin being given the coordinates x = 609,601.22metres, y = 0 metres. The precise position of said system shall be as marked onthe ground by triangulation or traverse stations or monuments established inconformity with the standards adopted by the National Geodetic Survey for first‑and second‑order work, whose geodetic positions have been rigidlyadjusted on the North American Datum of 1983, and whose plane coordinates havebeen computed on the system defined. Whenever plane coordinates are used in thedescription or identification of surface area or location within this State,the coordinates shall be identified as "NAD 83", indicating NorthAmerican Datum of 1983, or as "NAD 27", indicating North AmericanDatum of 1927.
