| Abstract: | In this paper some methodical aspects concerning the construction of an accurate geodetic network in arid areas and the connection of the new points to an existing network are discussed. In this context special attention is rapid on the determination of the station heights above the geoid. For the Western Desert in Egypt, which can be regarded as an example of an arid, geodetically underdeveloped region, an observational program is outlined that combines Doppler-measurements with an astrogravimetric-levelling. |
