Hello, I have a problem with snap. I never worked with it. I need to make DEM. The only thing I know is that it’s possible to make DEM via building a graph. But when I’m trying to make it, the error “S1 TOPS SLC Products should use TOPS Coregistration” appears. What should I do?
Creating a DEM by graph is not a good idea because you should keep track of the outputs of the single steps.
It’s well explained here:
This error means that you should use TOPS coregistration for S1 TOPS SLC products. You can find it in the radar menus.
Hello, I’m here with problem again. I know here a lot of people who made DEM. I really need your help. I need DEM but I have no idea how to make it. If you know how to do it please message me to firstname.lastname@example.org. We will discuss work and rewarding for it. Please, my study in university depends on it. Please, help me
You need to go through the tutorials for S1TBX & SNAP. DEM generation is not simple and the end result is likely to be poor due to the effect of the atmosphere.
