Abstract
In 1995 at the IUGG-meeting in Boulder, the project of recomputation of the Austrian geoid under the title GEOID2000 was announced. The aim of this project is to get a geoid with an absolute accuracy of one centimeter. One of the studies within this project is dedicated to the computation of a pure gravimetric geoid and the accuracy which can be reached.
The present gravimetric geoid is computed by the remove-restore technique on the basis of the geopotential model EGM96 and a high resolution height model of Austria with a grid distance of 44 m × 49 m. Stokes’ formula was evaluated by 2D FFT with the software package GRAVSOFT (Tscherning et al., 1991). An external check of the resulting geoid heights was done with the help of GPS reference points.
