Dear s1tbx team,
I get the error in subject for a SRTM 1Sec HGT tile that was written to .snap/auxdata/dem/SRTM\ 1Sec\ HGT/ in a previous run (doing Terrain-Correction on a GRD tile). I have not changed anything in between runs. The process continues by downloading the tile from http://step.esa.int/auxdata/dem/SRTMGL1/ (twice! and once for N55E022).
GRD scene is: S1A_IW_GRDH_1SDV_20180523T043513_20180523T043538_022027_02614F_D349.zip
Although marked as SEVERE, the process completes fine. However, over scenes which are including non-existing SRTM tiles over sea (which I replace by empty “fake” tiles) this error breaks the process, obviously because it will never find the fake tile on the ESA server.
What is the reason for the error and can it, somehow, be circumvented?
