Name: NAD83 to NAD83(CSRS)v3 (2)
Method: NTv2
Grid Files: SK83-98.gsb
Remarks: Can be taken as an approximate transformation NAD83 to WGS 84 - see code 1697.

Revision date: 2020-01-16
Unit: US survey foot
Geodetic CRS: NAD83
Datum: North American Datum 1983
Ellipsoid: GRS 1980
Prime meridian: Greenwich

Scope: Engineering survey, topographic mapping.
Remarks: State law defines system in US survey feet. Federal definition is metric - see code 26943. For applications with an accuracy of better than 3 feet, replaced by NAD83(HARN) / SPCS.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: ftUS.
