Harp Piemonte — PS SqueeSAR Radarsat

Dataset of points related to the results of the survey campaign using SqueeSAR radar-satellite technology. The SqueeSAR technique allows to detect the movement over time of objects to the ground (typically manufactured or exposed rock) that are good radar reflectors. The processing was carried out by the Tele sensing Europa TRE in Milan (spin-off of Politecnico di Milano) on radar images taken from the Radarsat satellite platform between 2003 and 2009; therefore, all the information provided relates to this time interval. Proper use of the data made available by the service requires knowledge of the principles of the method, its limits and the methods used for processing. Uncritical use of data and lack of knowledge of the limitations of the method may lead to misinterpretation, in particular as regards assessments of landslides. The speed figure is expressed in mm/year
