Geodetic CRS: ETRS89-MDA [MOLDREF99]
Datum: MOLDREF99
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: IOGP
Revision date: 2025-10-28
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-MDA [MOLDREF99] anchor epoch of 1997.4 but deteriorates with time due to tectonic deformation and/or glacial isostatic adjustment.
Method: Geocentric translations (geocentric domain)
Area of use: Moldova.
