we must still organize the data base and think how to manipulate the large amount of data. New advances arise continuously in the storage, retrieval and data interpretation, including spatial and temporal variations. Between Umbria (Norcia area), Abruzzo and southern Lazio (Sora area) regions, was set up and surveyed a GPS network. This paper illustrates a GIS developed as a geodetic project, funded by the Italian Space Agency, to evaluate the present day crustal deformation of the Central Apennine region (Central Italy) by space geodesy techniques. The GIS uses space based integrated observations, such as GPS, DinSAR and remote sensing. Estimate geodetic deformation in high risk seismic area that experienced past destructive earthquakes and investigate active faults and seismogenic...
