EPSG:2905

NAD83(HARN) / New York East (ftUS)

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Approximation derived from tfm code 6864 ignoring time-dependent parameters and assuming ITRF96(1997.0) and WGS 84, plus NAD83(CORS96) and NAD83(HARN), can be considered the same within the accuracy of the tfm. In USA only replaces tfm code 1900.

Information source: 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 2828. Replaces NAD83 / SPCS for applications with an accuracy of better than 3 feet. Replaced by NAD83(NSRS2007) / SPCS.

Area of use: United States (USA) - New York mainland - counties of Albany; Clinton; Columbia; Delaware; Dutchess; Essex; Franklin; Fulton; Greene; Hamilton; Herkimer; Montgomery; Orange; Otsego; Putnam; Rensselaer; Rockland; Saratoga; Schenectady; Schoharie; St Lawrence; Sullivan; Ulster; Warren; Washington; Westchester.

Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: ftUS.
