ABSTRACT
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.
