Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: Boucher and Altamimi "Memo : Specifications for reference frame fixing" v8 and EUREF Technical Note 1: Relationship and Transformation between the International and European Terrestrial Reference Systems, Nov. 16, 2017.
Revision date: 2025-02-19
Scope: Geodesy.
Remarks: Defined by transformation from ITRF2005 (CT 5900). On publication in 2007 of this reference frame, the EUREF TWG recommended that ETRF2000 rather than this reference frame remained as the preferred realization of ETRS89. Replaced by ETRF2014 (code 1206).
Area of use: Europe - onshore and offshore - ETRF extent - approximately 16°W to 33°E and 33°N to 84°N.
