Insar and Polinsar for Land Subsidence Monitoring User Perspective

In this paper the selected interferometric studies of subsidence caused by underground mining are discussed. Despite the common limitations the traditional single-polarization InSAR technique is already proved its high potential in this application. Today, the determination of the areas of affected by terrain deformation risks becomes one of the most promising applications for operational use of SAR data. InSAR monitoring of Upper Silesian Coal Basin in Poland (ESA AO3-127 project) and other studies from Central Europe shows that the interpretation of the fringe pattern is often strongly reduced by low coherence. On the base of these examples this paper aims to discuss a potential advantages of POLinSAR technique in this application.
