Geodetic CRS: ETRS89
Datum: European Terrestrial Reference System 1989 ensemble
Data source: EPSG
Information source: IOGP
Revision date: 2021-01-13
Scope: Derivation of gravity-related heights from GNSS observations.
Remarks: This concatenated operation gives the same result as the HoehenGrid-plus offset from ETRS89 to GHA height. HoehenGrid-plus is implemented in BEV-Transformator using MGI (CRS 4312) as the interpolation CRS for the grid
Area of use: Austria.
