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.
