ETRF2000

Attributes

Unit: degree (supplier to define representation)

Geodetic CRS: ETRF2000

Datum: European Terrestrial Reference Frame 2000

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: IAG Sub-Commission for the European Reference Frame (EUREF, http://etrs89.ensg.ign.fr/) and Boucher and Altamimi "Memo : Specifications for reference frame fixing in the analysis of a EUREF GPS campaign" (http://etrs89.ensg.ign.fr/memo-V8.pdf)

Revision date: 2024-03-13

Scope: Geodesy.

Remarks: Replaces ETRF97 (code 7929). On the publication of ETRF2005 the EUREF Technical Working Group recommended ETRF2000 be the realization of ETRS89. ETRF2014 and ETRF2020 (codes 8403 and 10570) are technically superior to all earlier realizations of ETRS89.

Area of use: Europe - onshore and offshore - ETRF extent - approximately 16°W to 33°E and 33°N to 84°N.

Coordinate system: Ellipsoidal 3D CS. Axes: latitude, longitude, ellipsoidal height. Orientations: north, east, up. UoM: degree, degree, metre.
