OK,I have successfully do unwapping phase yesterday, I prepared to use TerraSAR-X data to do three-dimensional extraction of urban buildings. After unwapping phase,I want to know how to generate DEM in snap software.
In addition, I just use TerraSAR-X data to do Polarimetric. Processing is creating a subset>calibrating the data>polarimetric matrix generation, when I do polarimetric matrix generation, show that message:Input should be a polarimetric product. I use band is HH. How should I solve these problems?Thanks.
