ETRS89-DEU [ETRS89/DREF91/2025] to ETRF2020 (1)

Attributes

Geodetic CRS: ETRS89-DEU [ETRS89/DREF91/2025]

Datum: ETRS89/DREF91 Realization 2025

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: EUREF "Overview of national realizations of the integrated geodetic reference in Europe", https://doi.org/10.71603/NatRefEurope

Revision date: 2025-11-12

Scope: Merging of spatial data referenced to different national realizations of ETRS89 at the sub-decimetre level of accuracy.

Remarks: Derived from ITRF2020 to ETRF2020 (1) (CT code 10573) minus ITRF2020 to ETRS89-DEU [ETRS89/DREF91/2025 (1) (CT code 11204). Accuracy is approximately 1cm at the ETRS89-DEU [ETRS89/DREF91/2025] anchor epoch of 2021.48 but deteriorates with time due to tectonic deformation and/or glacial isostatic adjustment.

Method: Position Vector transformation (geocentric domain)

Area of use: Germany - onshore and offshore.
