Abstract :
Located in the Alta Badia Valley, a famous tourist area in the Dolomites of northern Italy, the active Corvara earthslide-earthflow causes damages to critical road infrastructures, as well as ski and other recreational facilities and power lines. The high spatial resolution and the short frequency of revisit time of COSMO-SkyMed system (CSK®), open new opportunities for SAR-based monitoring systems dedicated to natural risks management. The ASI AO funded project “LAWINA” takes advantage from these distinctive features together with non-conventional reflectors, in order to monitor and assess the hazard of such a phenomenon by means of PSI techniques. The particular working context and the complete processing workflow for this specific application, offer opportunity to highlight strengths and weak points of classical approach to PSI and to provides suggestions for an effective use of experimented corners.
