ETRS89-DNK

Attributes

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: Geodesy and Surveying Division, Danish Agency for Climate Data; https://www.klimadatastyrelsen.dk/

Revision date: 2025-08-24

Scope: Geodesy.

Remarks: The Danish ETRS89 realization was originally based on seven passive stations which over time have shown some instability. To remedy this, the Danish ETRS89 realization was updated in 2019 to include CORS stations. ETRS89 coordinates for the CORS stations were determined using a Helmert transformation that included observation of both the original passive stations and the CORS stations. The updated coordinates were determined in 2015, and hence, the intra-plate deformation epoch has changed to 2015.829 from the original epoch of 1992.7. Formally, the realization is unchanged, but in practice, the realization is now carried by the more geodynamically stable CORS stations.

Area of use: Denmark - onshore and offshore.
