Revisiting Czech System for InSAR Monitoring Using Sentinel-1 Data

Abstract

This contribution will revisit a complex system established to prepare analysis ready data from Copernicus Sentinel-1 satellite system, primarily to allow independent interferometric (InSAR) measurements of terrain deformation over Czechia, in both local and nation-wide scale. With the high revisit rate of 6 days, medium ground resolution of several meters and sensitivity to millimetric motion in the satellite line of sight (LOS), the quality of InSAR results from Sentinel-1 are applicable practically. This contribution will present results over selected areas of interest in Czechia, where a subsidence or other deformation was detected.
