Method: NADCON5 (3D)
Grid Files: nadcon5.nad83_1997.nad83_2002.prvi.lat.trn.20160901.b nadcon5.nad83_1997.nad83_2002.prvi.lon.trn.20160901.b
Remarks: Uses NADCON5 method which expects longitudes positive east in range 0-360°; EPSG source and target CRSs have longitudes positive east in range -180° to +180°.
Information source: National Geodetic Survey, www.ngs.noaa.gov
Revision date: 2018-07-17
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: Not applicable to offshore areas. State law defines system in US survey feet. Federal definition is metric - see code 2801. Replaces NAD83 / SPCS for applications with an accuracy of better than 3 feet. Replaced by NAD83(NSRS2007) / SPCS.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: ftUS.
