The Italian Gravimetric Geoid
A new step of the Italian geoid has been almost completed. The geoid has been computed all over the Italian territory using a new gravity data base and a global model. The computation has been partly repeated using a digital height model too in order to separate the terrain effects; this job is still in development.
The data menagement and the computational activities are reported in this paper and the results are presented and discussed.
