I have a problem that has already been addressed here, but I believe that these were special cases.
I want to say in advance that I apologize for the text, because I am from Russia and I can only interact with English through a translator.
The case is as follows: I performed the tutorial " TRAINING KIT CRYO02 (GLACIER VELOCITY WITH SENTINEL-1 USING SNAP S-1 TOOLBOX-PETERMAN GLACIER, GREENLAND)".
At one of the stages, namely Terrain correction, after set the product as the Source Product and In the Processing Parameters tab set:
Digital Elevation Model: ACE30 (Auto Download)
Map Projection: Custom CRS (EPSG: 32621 – WGS84 / UTM Zone 21N) and startup, I got this error.
Unfortunately, I am a very novice specialist. I started working with the program and this tutorial for the first time today. I can’t figure out how to fix the error and whether it’s possible.
I will attach this tutorial as a link. If anyone has time to help me, I would be very grateful.
