Name: NAD83 to WGS 84 (8)
Remarks: The gridded difference file AB_CSRS.DAC in STEP 1 will need to be renamed to AB_CSRS.gsb to run in some software suites. Formats identical, but AB file is provincial fit only.

Revision date: 2000-10-19
Unit: US survey foot
Geodetic CRS: NAD83
Datum: North American Datum 1983
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG

Revision date: 2001-11-06
Scope: Engineering survey, topographic mapping.
Remarks: State law defines system in US survey feet. Federal definition is metric - see code 26987. For applications with an accuracy of better than 3 feet, replaced by NAD83(HARN) / SPCS.
Area of use: United States (USA) - Massachusetts offshore - counties of Dukes; Nantucket.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: ftUS.
