Hello,
I am discovering your pipeline as I would like to generate DEMs for a glacier in Alaska. I tried different AOIs, different times and sizes, and I am always blocked at the same step: generating the DEMs with 2_dem_generation.py.
The script encounters the following error:
Traceback (most recent call last):
File "/scripts/2_dem_generation.py", line 941, in <module>
subset_buffer=args.aoi_buffer
File "/scripts/2_dem_generation.py", line 683, in run_P1_interferogram
pass_metadata_p1 = product_1.getMetadataRoot() \
AttributeError: 'NoneType' object has no attribute 'getMetadataRoot'
I traced it back to SNAP, and concluded that it could come from bad images, but even after changing AOI and time-window I still got the same issue. Depending on which AOI or which time-window I use, I get between 2 and 10 .zip images.
Have you encountered that issue before ? If not, could you recommend an area that you know that works well with the code ?
Thank you !
ps: it's awesome to see people finally creating a pipeline for SAR DEM generation !!
