ABSTRACT
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.
