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.
Unfortunately, the problem was not resolved. I tried to select a different zone, but the error still exists.
Can I ask how important this stage is for further glacier velocity calculation and data visualization? Can I skip it, or will I not be able to go any further?
This is a glacier in Greenland, suggested by this tutorial. The data I downloaded differs only in the year, since the tutorial was in 2017, and data from 2017 is not available on Copernicus.
