Name: NAD83 to NAD83(CSRS)v4 (3)
Method: NTv2
Grid Files: AB_CSRS.DAC
Remarks: This gridded difference file AB_CSRS.DAC may need to be renamed to AB_CSRS.gsb or AB_CSRSV4.gsb to run in some software. Formats identical, but AB file is provincial fit only. Can be taken as an approximate transformation NAD83 to WGS 84 - see code 1702.

Revision date: 2023-07-17
Unit: metre
Geodetic CRS: NAD83
Datum: North American Datum 1983
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG

Scope: Engineering survey, topographic mapping.
Remarks: State law defines system in US survey feet. See code 2264 for equivalent non-metric definition. For applications with an accuracy of better than 1m, replaced by NAD83(HARN) / SPCS.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
