Method: Coordinate Frame rotation (geog2D domain)
Remarks: Approximation derived ignoring time-dependent parameters and assuming ITRF94(1996.0) and WGS 84, plus NAD83(CORS94) and NAD83(HARN), can be considered the same within the accuracy of the transformation. Replaced by NAD83(HARN) to WGS 84 (3) (code 1901).
Information source: US National Geodetic Survey http://www.ngs.noaa.gov/CORS/Derivation.html
Revision date: 2021-09-08
Unit: US survey foot
Geodetic CRS: NAD83(HARN)
Datum: NAD83 (High Accuracy Reference Network)
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 2806. Replaces NAD83 / SPCS for applications with an accuracy of better than 3 feet. Replaced by NAD83(NSRS2007) / 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.
