Selected transformation

Name: NATRF2022 to WGS 84 (1)

Method: Geocentric translations (geog2D domain)

Remarks: For many purposes NATRF2022 can be considered to be coincident with WGS 84. This approximation ignores the low accuracy of the WGS 84 ensemble and the application of tectonic plate motion to WGS 84 data.

Revision date: 2025-08-11

Attributes

Unit: foot

Geodetic CRS: NATRF2022

Datum: North American Terrestrial Reference Frame of 2022

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: U.S. National Geodetic Survey, https://www.ngs.noaa.gov/

Revision date: 2025-08-11

Scope: Emulation of SPCS27.

Remarks: Emulates most of offshore area of NAD27 / BLM zone 16 (ftUS) (CRS code 32066) to better than 6 ft, but south of 26°N differences can exceed 15ft. Emulation embeds change of ellipsoid and of unit (ftUS to ft). Note: SPCS2022 CRSs normally have axis order N-E; this emulation of SPCS27 uses SPCS27 order east (X) - north (Y).

Area of use: USA - Gulf outer continental shelf (GoM OCS) deep water between approxinately 90°W and 84°W - protraction areas Mobile, Viosca Knoll, Mississippi Canyon, Atwater Valley, Lund, Lund South, Pensacola, Destin Dome, De Soto Canyon, Lloyd Ridge, Henderson, Florida Plain, Campeche Escarpment, Apalachicola, Florida Middle Ground, The Elbow, Vernon Basin, Howell Hook, Rankin.

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