Abstract

The choice of the best geopotential model to reduce geodetic data is one of the critical step in computing the geiod. In this paper, both gravity and altimetry were considered on a large area covering the Mediterranean Sea; an analisys was carried out to define the “best” geopotential model in this area. Six models were considered and statistical tests were performed on the residual data (i.e. observed data minus model).
