Geodetic CRS: ITRF2014
Datum: International Terrestrial Reference Frame 2014
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: Häkli et al., "NKG2020 transformation: An updated transformation between dynamic and static reference frames in the Nordic and Baltic countries"; Journal of Geodetic Science 2023; 13: 20220155, https://doi.org/10.1515/jogs-2022-0155.
Revision date: 2025-10-20
Scope: Geodesy.
Remarks: The coordinate epoch (in years) of the coordinates referenced to the source CRS (ITRF2014) is user-defined and is used as the source epoch in step 2. For coordinates originating before 2021-02-07, the NKG2008 transformation should be used.
Area of use: Sweden - onshore and offshore.
