Abstract

An increasing demand for local or national geoids results of the development of GPS positioning. In order to determine the precision that could be reached in heights determination with different data and methods, a test network covering 560 km2 was established in 1993–1994. 63 points were observed with GPS and precise levelling in a hilly area located in the South of France. Gravity measurements and a digital terrain model were also available. Two methods are compared. The first one is based on simple interpolation, the second one uses a gravimetric geoid and greatly improves the precision.
