Cosmo-SkyMed versus TerraSAR-X -based interferometry for monitoring the MOSE settlements at the Venical Lagoon inlets

The modern approach of studying ground movements is aimed at distinguishing regional land subsidence and local consolidation processes, as well as long- and short- term displacements. With a very-high resolution images and a repeatability acquisitions never available in the past the new generation of SAR satellites provides helps to reach these achievements. In this work we compare the capability of Cosmo-SkyMed and TerraSAR-X for detecting the displacement of jetties, breakwaters, locks, and an artificial island which are under construction in the Venice lagoon inlets, Italy, as part of the anti-flood project MOSE Cosmo-SkyMed and TerraSAR-X have been also used to provide an updated quantification of the subsidence rates of the Venice and Chioggia historical centers.
