Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: Norwegian Mapping Agency (Kartverket) report 19-04811-18 "Referanserammer og transformasjoner", 19 October 2023; https://www.kartverket.no/
Revision date: 2026-07-21
Scope: Geodesy, cadastre, engineering survey, topographic mapping.
Remarks: EUREF89 is the Norwegian realization of ETRS89. It was realized with GPS campaigns in 1994-1996. Resulting ITRF93 coordinates at epoch 1995.0 were transformed to ETRF93 (for which frame reference epoch is 1989.0) according to EUREF Technical Note 1. These formulas correct only for rigid plate motion, but not intraplate deformations.
Area of use: Norway including Svalbard - onshore and offshore.
