Geoid model CHGeo2004 in ETRS89
Swiss geoid model in the version of 2004 (CHGeo2004) in the reference system ETRS89. It forms the zero reference surface (approximated mean sea level) for height determination and serves for the transformation between ellipsoidal heights and orthometric heights (LHN95). The geoid heights are stored in a regular 30 x 30 seconds grid and are interpolated by the biquadratic method. The model is available in various reference systems and data formats.
