I want to use an external DEM, and I selected it at the DEM source at coregistration parameters, but when I try to run coregistration I get the error I listed below this message.
I have tried 2 DEM .tif files:
– High Mountain Asia from NSIDC
– AW3D30 from JAXA
and they definitely cover the selected area.
I want to use a different DEM than the provided SRTM as I want more current data as I am researching from 2015-2021 (and a DEM more suitable for the Himalayas where the choice of DEM can have a big influence I believe).
What am I doing wrong? (everything does work when using the default SRTM)
Thanks in advance!
