Land subsidence monitoring service in the Lagoon of Venice

In order to provide the best knowledge of the subsidence process around the Lagoon of Venice to the authorities that manage the area, SAR-based monitoring techniques (differential SAR interferometry and the interferometric point target analysis) will be integrated with levelling and GPS surveys into an overall database and information system. In this contribution the different monitoring techniques are briefly introduced, the results presented and compared, and the integration concept explained.
