Geodetic CRS: ETRS89-GBR [OSNet v2009]
Datum: OSNet v2009
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: IOGP
Revision date: 2025-10-17
Scope: Merging of spatial data referenced to different national realizations of ETRS89 at the sub-decimetre level of accuracy.
Remarks: Accuracy is approximately 1cm at the ETRS89-GBR [OSNet v2009] anchor epoch of 2009.756 but deteriorates with time due to tectonic deformation and/or glacial isostatic adjustment.
Method: Geocentric translations (geocentric domain)
Description: (0,)
