Description:
Italian Quasi-Geoid computed at Politecnico di Milano. The area covered by the estimate is 35° < lat < 48°, 5° < lon < 20° with grid spacing of 2' both in latitude and in longitude. The computation is based on remove-restore technique and fast collocation; the solution was obtained in one step only over the whole area. The gravimetric geoid, integrated with GPS/levelling data, has an overall precision of around 3 cm over the entire Italian area.
