Abstract :
This work concerns the application of groundbased SAR interferometry (GB-InSAR) for the monitoring of the Tessina landslide, using the LISA (Linear SAR) system developed at the JRC. This landslide is continuously monitored by a topographic system. For this reason it has been chosen as a test site to fully confirm the accuracy of the, GB-InSAR. The GB-InSAR-derived ground displacements have been compared with those obtained by a set of topographic benchmarks placed in the unstable areas.
