DInSAR Data for Landslides in Basilicata Region: Geotechnical Calibration and Interpretation

The urbanized slopes facing the Basento river valley are affected by many landslides of different types. For several places, DInSAR displacement data as well as digital terrain and surface models (DTM and DSM) were elaborated. SAR COSMO-SkyMed and Sentinel-1 images were processed to evaluate the displacements along the LOS of available scatterers over about the last ten years, LiDAR point clouds were processed for DTM and DSM with 1 m spatial resolution. For two case studies, sufficient inclinometer data were also available, thus it was possible to extend in space and in time reliable information on the landslides and their effects on the built environment. It was therefore possible to locate zones at high risk and to evaluate the effects of remedial measures.
