SATELLITE INSAR GEODETIC DEFORMATION MONITORING SERVICES

SATELLITE INSAR GEODETIC DEFORMATION MONITORING SERVICES

The purpose of the work is to use satellite DInSAR to monitor surface deformation on several areas of interest.

The SAR revisits the same area at regular intervals, providing then information about the observed scene with very high spatial resolution. The Differential SAR Interferometry (DInSAR) technique allows to measure the changes of the surface and measure the displacement with high accuracy. The interferometric techniques produce maps of ground deformation and is possible to follow the temporal evolution of a deformation when using a series of images acquired over time.

In particular, CNIT is in charge of analyzing some regions of interest by using data (including historical data-sets) acquired by RADARSAT1, RADARSAT2, COSMO-SkyMed and TerraSAR-X.
