Quasigeoid 2011 of the Federal Republic of Germany

The satellite geodetic-nivellitic-gravimetric quasigeoid model of the Federal Republic of Germany describes the elevation reference area of the country survey over the referenceellipsoid of the geodetic reference system 1980 (GRS80). It enables the transformation between satellite geodetic determined ellipsoidal heights in ETRS89 and nivellitically determined physical heights (DHHN92) with an accuracy of 1-2 cm. The geoid model is delivered for the entire territory of the FRG or in five subregions. These sub-regions include: Northeast: Berlin, Brandenburg, Mecklenburg-Western Pomerania, Saxony, Saxony-Anhalt, Thuringia; South: Baden-Württemberg, Bavaria; West: Hessen, Nodrhein-Westfalen, Rhineland-Palatinate, Saarland; Northwest: Bremen, Hamburg, Lower Saxony, Schleswig-Holstein; Coast: Marine areas up to 55.2° North or for the area of the exclusive economic zone of Germany (North Sea). The grid width in each model is 1x 1.5 in geographical coordinates.
