Problem with snap (creating DEM)


#1

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.

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.
