LAND SUBSIDENCE MONITORING TECHNIQUES A NEW STRATEGY ADOPTED IN THE VENETIAN AREA, ITALY

Among recent research topics dealing with land subsidence in the Venice region, great attention has been given to monitoring techniques. Recently, SAR-based analyses have been used to complement the ground-based methods, and an integrated monitoring system based on levelling, GPS, and InSAR techniques (SIMS), able to optimize the areally distributed information and to provided synoptic maps of ground surface displacements with high accuracy and reliability for both small areas and al regional scale was developed.
