Extraction of polarimetric information from SAR data is one of the most important issues in SAR applications. Since fully polarimetric SAR data and model-based scattering power decomposition are now available, its real utilization becomes important topic. In this presentation, some data sets from PiSAR-L2, ALOS, ALOS-2 systems are shown using the existing model-based scattering power decompositions. The observation areas are chosen so that each scattering mechanism correspond specific scattering power utilization, i.e., landslide area for the surface scattering, urban expansion for the double bounce scattering, deforestation for the volume scattering. The final color-coded images provide us with direct way to understand the scattering scenario in the real world.
