Sentinel-1 data for ground deformation monitoring: the SNAP-StaMPS workflow

During the last decades, radar interferometry has become an effective technique able to provide reliable information in a variety of applications such as geodesy, natural hazards assessment, ground deformations and monitoring. With the beginning of Copernicus Earth Observation program, new chances in Earth Observation field arose. For instance, Sentinel-1A and -1B provide synthetic aperture radar acquisitions over very large areas at average spatial resolution and very short revisit time, thus increasing the opportunities offered by existing radar satellite. In this work we assess the potentialities of Sentinel-1 data by the generation of displacements maps through the PSInSAR techniques and a processing workflow including the free Sentinel Application Platform (SNAP) and Stanford Method for Persistent Scatterers (StaMPS) software package. Results are referred to a couple of areas affected by ground deformation.
