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.

Scope: Engineering survey, topographic mapping.
Remarks: State law defines system in International feet (note: not US survey feet). Federal definition is metric - see code 26948. For applications with an accuracy of better than 3 feet, replaced by NAD83(HARN) / SPCS.
Area of use: United States (USA) - Arizona - counties Apache; Cochise; Gila; Graham; Greenlee; Navajo.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: ft.
