(FOR CONTINGENT EFFECTIVE DATE, SEE ACTS 2025, CC. 91 AND 109, CL. 2) DEFINITION
OF SYSTEMS BY NATIONAL OCEAN SERVICE/NATIONAL GEODETIC SURVEY; ADOPTED (§
1-605)

A. For purposes of more precisely defining the Virginia Coordinate System of
1927, the following definition by the National Ocean Service/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&#xB0; 02&#8242; and 39&#xB0; 12&#8242;, along which parallels the
scale shall be exact. The origin of coordinates is at the intersection of the
meridian 78&#xB0; 30&#8242; west of Greenwich with the parallel 37&#xB0;
40&#8242; north latitude, such origin being given the coordinates: x =
2,000,000&#8242; and y = 0&#8242;.
			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&#xB0; 46&#8242; and 37&#xB0; 58&#8242;, along which parallels the
scale shall be exact. The origin of coordinates is at the intersection of the
meridian 78&#xB0; 30&#8242; west of Greenwich with the parallel 36&#xB0;
20&#8242; north latitude, such origin being given the coordinates: x =
2,000,000&#8242; and y = 0&#8242;.

B. For purposes of more precisely defining the Virginia Coordinate System of
1983, the following definition by the National Ocean Service/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&#xB0; 02&#8242; and 39&#xB0; 12&#8242;, along
which parallels the scale shall be exact. The origin of coordinates is at the
intersection of the meridian 78&#xB0; 30&#8242; west of Greenwich and the
parallel 37&#xB0; 40&#8242; north latitude, such origin being given the
coordinates: x = 3,500,000 meters and y = 2,000,000 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&#xB0; 46&#8242; and 37&#xB0; 58&#8242;, along
which parallels the scale shall be exact. The origin of coordinates is at the
intersection of the meridian 78&#xB0; 30&#8242; west of Greenwich and the
parallel 36&#xB0; 20&#8242; north latitude, such origin being given the
coordinates: x = 3,500,000 meters and y = 1,000,000 meters.

C. For purposes of more precisely defining the Virginia Coordinate System of
2022, the following definition by the National Ocean Service/National Geodetic
Survey is adopted:
			The Virginia Coordinate System of 2022, North Zone, is a Lambert conformal
conic, one parallel projection based on the North American Terrestrial Reference
Frame of 2022, having one standard parallel at north latitude 38&#xB0;
36&#8242;, along which parallel the scale shall be exact. The origin of
coordinates is at the intersection of the meridian 78&#xB0; 15&#8242; west of
Greenwich and the parallel 38&#xB0; 36&#8242; north latitude, such origin being
given the coordinates: x = 457,200 meters and y = 190,500 meters.
			The Virginia Coordinate System of 2022, South Zone, is a Lambert conformal
conic, one parallel projection based on the North American Terrestrial Reference
Frame of 2022, having one standard parallel at north latitude 37&#xB0;
21&#8242;, along which parallel the scale shall be 0.999990. The origin of
coordinates is at the intersection of the meridian 79&#xB0; 30&#8242; west of
Greenwich and the parallel 37&#xB0; 21&#8242; north latitude, such origin being
given the coordinates: x = 685,800 meters and y = 190,500 meters.
