Name: NAD83 to WGS 84 (56)
Method: NADCON
Grid Files: schpgn.las schpgn.los
Remarks: Parameter files are from NAD83 to NAD83(HARN) (45) (code 15836) assuming that NAD83(HARN) is equivalent to WGS 84 within the accuracy of the transformation.
Information source: OGP
Revision date: 2021-09-10
Unit: US survey foot
Geodetic CRS: NAD83
Datum: North American Datum 1983
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: National Geodetic Survey
Revision date: 2016-07-13
Scope: Engineering survey, topographic mapping.
Remarks: State law defines system in US survey feet. Federal definition is metric - see code 26982. 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.
