Not really, because SNAP simply can’t terrain correct SLC quadpol data downloaded from ESA (only from ASF)
older question I posted regarding that.
The thing it can do though is to write the geocoding by a workaround, that is mosaicing only one image. In my case it is ok since it is a really flat area and my specific areas are actually exactly where then need to be without any foreshadowing and such.
So in my case geocoding is not terrain correcting. But that shouldn’t really matter.
Even if we remove the geocoding or terrain correcting step, the issue is still that I need to speckle filter so I can analyze the results.
