Hi, I have a problem with the Range Doppler Terrain Correction. When I try to correct with deafult options the image just doesnt show it is plain black, but ir does work with Ellipsoid correction. I was wondering why is that?

Hey, I had the same problem. Update your SNAP software to the latest edition, and try again. Hope it works.

Hey, I had the same issue where the default instructions only resulted in a blank screen for the Terrain Correction step. I suspect it was due to the SRTM DEM not being downloaded. I used the SRTM 1Sec HGT (Auto Download) DEM instead, and this worked for me. I could see the DEM being downloaded in the bottom status bar, and the resultant images worked

It happened to me as well and what I did was to close the pop-up it started updating itself, not the program, but the plugins also, then I did the geometric correction and it worked
