Section 47-1-53 - Definition of coordinate system according to U.S. coast and geodetic survey [national ocean survey and national geodetic survey]A. For purposes of more precisely defining the New Mexico coordinate system, the following definition by the national ocean survey and national geodetic survey is adopted: (1) the New Mexico coordinate system, east zone, is a transverse mercator projection having a central meridian 104° 20' west of Greenwich, on which meridian the scale is set at one part in 11,000 too small. The origin of coordinates is at the intersection of the meridian 104° 20' west of Greenwich and the parallel 31° 00' north latitude; (2) the New Mexico coordinate system, central zone, is a transverse mercator projection having a central meridian 106° 15' west of Greenwich, on which meridian the scale is set at one part in 10,000 too small. The origin of coordinates is at the intersection of the meridian 106° 15' west of Greenwich and the parallel 31° 00' north latitude; (3) the New Mexico coordinate system, west zone, is a transverse mercator projection having a central meridian 107° 50' west of Greenwich, on which meridian the scale is set at one part in 12,000 too small. The origin of coordinates is at the intersection of the meridian 107° 50' west of Greenwich and the parallel 31° 00' north latitude; and (4) the origin for each zone is assigned the coordinates: x = 500,000 feet and y = 0 feet for the New Mexico coordinate system of 1927. The origin for the east zone is assigned to the coordinates: x = 165,000 meters and y = 0 meters, for the central zone x = 500,000 meters and y = 0 meters and for the west zone x = 830,000 meters and y = 0 meters for the New Mexico coordinate system of 1983. B. The position of the New Mexico coordinate system shall be as marked on the ground by horizontal control stations established in conformity with standards adopted by the national ocean survey and national geodetic survey for first-order, second-order and third-order work, whose geodetic positions have been rigidly adjusted on the North American datum of 1927 or of 1983, and whose coordinates have been computed on the system defined in this section. Any such station may be used for establishing a survey connection with the New Mexico coordinate system. 1953 Comp., § 70-1-51, enacted by Laws 1957, ch. 147, § 5; 1989, ch. 104, § 5.
