NAD83(HARN) / Massachusetts Island (ftUS)

Selected transformation

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

Attributes

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.
