In the framework of the GEOMED2 project, the geoid over the Mediterranean area has been estimated based on the available gravity data. Land and ship-borne data have been collected and edited to derive a homogeneous and reliable dataset. Different Global Geopotential Models have been used when reducing for the low frequency component of the gravity signal and different approaches have been as well considered in accounting for the terrain effect. In estimating the geoid, Collocation, Stokes-Wong&Gore and the KTH methods have been applied to gravity data that has been gridded on a regular 2’× 2’ geographic grid in the area 30 < phi < 48, 10 < lambda < 40. The geoid estimates have been provided over the same regular grid and then compared with GPS/levelling data over Italy and Greece. The results obtained using the different methods are here presented and discussed. |
