GROUND DEFORMATION ANALYSIS USING BASIC PRODUCTS OF THE COPERNICUS GROUND MOTION SERVICE

Abstract. Monitoring ground deformation at national and regional level with millimetre-scale precision, nowadays, is possible by using Advanced Differential Interferometric SAR (A-DInSAR) techniques. This study concerns the results of European Ground Motion Service (EGMS), part Copernicus Land Service, which detects measures land displacement scale. provides reliable consistent information regarding natural motion phenomena such as landslides subsidence. The derived from Synthetic Aperture Radar (SAR) time-series analysis Sentinel-1A/B data. These data, provide full coverage Europe two different observation geometries (ascending descending) every six days, are processed resolution. paper focused on exploitation basic product EGMS for both local purposes. Analysing slope aspect field novelty this investigation. In particular, focus put generation wide-area differential maps. Such maps indicate gradient field. obtained not only beneficial monitoring anthropogenic but also vital urban management planning. Most significant damages to manmade structures infrastructures associated high values. Thus, temporal spatial variations essential dynamic analysis, early-warning, risk assessment in areas. Although productions prepared level, their resolutions enough investigate level. Therefore, considers deformations that affect single or infrastructures. Local differences can corresponding We illustrate these types generate datasets available CTTC.
