Method: Geocentric translations (geog2D domain)
Remarks: Derived at 354 stations.
Information source: U.S. Defense Mapping Agency TR8350.2 revision of August 1993.
Revision date: 2014-11-19
Unit: US survey foot
Geodetic CRS: NAD83
Datum: North American Datum 1983
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: OGP

Revision date: 2013-11-05
Scope: Large and medium scale topographic mapping and engineering survey.
Remarks: State law defines system in US survey feet. Federal definition is metric - see code 26976. For applications with an accuracy of better than 3 feet, replaced by NAD83(HARN) / SPCS.
Method: Geocentric translations (geog2D domain)
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: ftUS.
