stackSentinel.py - run_01_unpack_topo_reference - ERROR 4: demLat_*.dem.wgs84.vrt: No such file or directory

[Edda1824]

Hi, I have tried to process stacks of Sentinel1 datasets (starting with only 20 scenes). However, I encountered this error when I tried to run the first run_files (run_01_unpack_topo_reference) for Sentinel1 stack processing. It seems GDAL is unable to find the dem VRT file, although its in the path directory folder. Could anyone help on how to solve this issue? Thanks in advance.

Here is part of the processing...
...

No existing stack was identified. A new stack will be generated.

在config文件夹中，找到config_reference文件，修改DEM路径

[Edda1824]

Thanks

In which path did you run the run_01 command? I had the same error, the solution was to switch to the folder where the dem is stored and open the terminal with... /Stacks/run_files/run_01_ to run the command. It seems that the reason for this error is that the program restricts the opening of the dem.vrt file to relative paths only!

Thanks!

After setting the path directory in config_reference and also running it in DEM folder, it solved the problem. However, I faced a new error when running the run_01_unpack_topo_reference similar to this thread #212 Appreciate your help. Thanks

New Error faced (Refer to thread #212 link):
