Satellites constellation Sentinel-1 provide costless SAR (Synthetic Aperture Radar) images of global range. Scientific institutions operating with SAR data received the great opportunity for carrying out continuous observations of the Earth. This kind of policy affects the efficiency of performed research and has direct impact on the safety in case on environmental threats. It is possible to monitor ground deformations of endangered areas. Sentinel-1 datasets have great potential in PSInSAR (Persistent Scatterer I...

This work presents improvement of land subsidence monitoring obtained by combining results of Sentinel-1A and Sentinel-1B data processing. In presented work DInSAR (Differential Interferometry SAR) technique was used. Results of DInSAR technique provide information about values of vertical deformation of the surface. Using this technique the areas endangered by subsidence phenomenon can be identified and appropriate steps in order to save the infrastructure, buildings, roads, and also human life can be taken. The ...
