Definitions of Nevada coordinate systems.
1.
For purposes of more specifically defining the Nevada Coordinate System of 1927, the following definition by the United States Coast and Geodetic Survey is adopted:(a)
The Nevada Coordinate System of 1927, East Zone, is a transverse Mercator projection of the Clarke Spheroid of 1866, having a central meridian 115°35¢ 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 115°35¢ west of Greenwich and the parallel 34°45¢ north latitude. This origin is given the coordinates: x = 500,000 feet and y = 0 feet.(b)
The Nevada Coordinate System of 1927, Central Zone, is a transverse Mercator projection of the Clarke Spheroid of 1866, having a central meridian 116°40¢ 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 116°40¢ west of Greenwich and the parallel 34°45¢ north latitude. This origin is given the coordinates: x = 500,000 feet and y = 0 feet.(c)
The Nevada Coordinate System of 1927, West Zone, is a transverse Mercator projection of the Clarke Spheroid of 1866, having a central meridian 118°35¢ 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 118°35¢ west of Greenwich and the parallel 34°45¢ north latitude. This origin is given the coordinates: x = 500,000 feet and y = 0 feet.2.
For purposes of more specifically defining the Nevada Coordinate System of 1983, the following definition by the National Geodetic Survey of the National Oceanic and Atmospheric Administration is adopted:(a)
The Nevada Coordinate System of 1983, East Zone, is a transverse Mercator projection of the North American Datum of 1983, having a central meridian 115°35¢ 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 115°35¢ west of Greenwich and the parallel 34°45¢ north latitude. This origin is given the coordinates: x = 200,000 meters and y = 8,000,000 meters.(b)
The Nevada Coordinate System of 1983, Central Zone, is a transverse Mercator projection of the North American Datum of 1983, having a central meridian 116°40¢ 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 116°40¢ west of Greenwich and the parallel 34°45¢ north latitude. This origin is given the coordinates: x = 500,000 meters and y = 6,000,000 meters.(c)
The Nevada Coordinate System of 1983, West Zone, is a transverse Mercator projection of the North American Datum of 1983, having a central meridian 118°35¢ 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 118°35¢ west of Greenwich and the parallel 34°45¢ north latitude. This origin is given the coordinates: x = 800,000 meters and y = 4,000,000 meters.
