For purposes of more precisely defining the Virginia Coordinate System of 1927, the following definition by the National Ocean Survey/National Geodetic Survey is adopted:

The Virginia Coordinate System of 1927, North Zone, is a Lambert conformal projection of the Clarke spheroid of 1896, having standard parallels at north latitudes 38° 02' and 39° 12', along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 78° 30' west of Greenwich with the parallel 37° 40' north latitude, such origin being given the coordinates: x2,000,000', and y0'.

The Virginia Coordinate System of 1927, South Zone, is a Lambert conformal projection of the Clarke spheroid of 1896, having standard parallels at north latitudes 36° 46' and 37° 58', along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 78° 30' west of Greenwich with the parallel 36° 20' north latitude, such origin being given the coordinates: x2,000,000', and y0'.

For purposes of more precisely defining the Virginia Coordinate System of 1983, the following definition by the National Ocean Survey/National Geodetic Survey is adopted:

The Virginia Coordinate System of 1983, North Zone, is a Lambert conformal conic projection based on the North American Datum of 1983, having standard parallels at north latitudes 38° 02' and 39° 12', along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 78° 30' west of Greenwich and the parallel 37° 40' north latitude. The origin being given the coordinates: x3,500,000 meters and y2,000,000 meters.

The Virginia Coordinate System of 1983, South Zone, is a Lambert conformal conic projection based on the North American Datum of 1983, having standard parallels at north latitudes 36° 46' and 37° 58', along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 78° 30' west of Greenwich and the parallel 36° 20' north latitude. This origin is given the coordinates: x3,500,000 meters and y1,000,000 meters.
