EPSG:9277

MGI to EVRF2000 Austria height (1)

Attributes

Geodetic CRS: MGI

Datum: Militar-Geographische Institut

Ellipsoid: Bessel 1841

Prime meridian: Greenwich

Data source: EPSG

Information source: Bundesamt für Eich- und Vermessungswesen (BEV).

Revision date: 2021-02-05

Scope: Derivation of gravity-related heights from GNSS observations.

Remarks: Austrian Geoid 2008 (Bessel ellipsoid). Accuracy 5cm (1 sigma). The transformation is implemented in BEV-Transformator. For reversible alternative to this transformation see MGI to MGI + EVRF2000 Austria height (1) (code 9601).

Method: Geographic3D to GravityRelatedHeight (BEV AT)

Area of use: Austria.
