Spatial and temporal analysis of interferometric data for ground deformation detection at regional scale

The goal of this Thesis work is to test and evaluate the feasibility of automated procedures for the management and for the analysis of large datasets of space-borne SAR data, processed by means of different PSI approaches, as operational tools for the spatial and temporal characterization of geohazards in different geological and geomorphological environments. In particular, three different and complementary approaches are proposed for the rapid detection, classification and characterization of the historical motion trend of areas of the territory suffering from significant surface displacements. Landslides, subsidence, mining-related displacements and many other natural or anthropogenic phenomena are evaluated with reference to their impact in terms of ground deformation intensity, deformation pattern and spatial occurrence.
