As is well known, GIS is a powerful tool to process, analyze and display spatial and temporal data whose standard applications are already tested and widely used in various application areas. At the laboratory of Geomatics, Mediterranean University of Reggio Calabria, we implemented a project for the complete realization of an open GIS for calculating the significance of the shifts resulting from GPS data acquired networks, repeated over time, without a priori information on the stability of the points themselves. The monitoring of geodynamic phenomena is constantly evolving thanks to the use of increasingly refined techniques. The increasing availability of data acquired over time, through the GPS system allows creating specific models able to simulate the situation in question. The main objective of this contribute is to provide the results from a long series of GPS data acquired over time on a network straddling an active fault, for the estimation of surface deformation in Castrovillari. The geodetic observations based on GPS can also provide useful information to the refinement of models of geophysical monitoring and prevention of natural disasters in areas of high seismic risk in presence of active faults.
