I am using the standalone sen2cor command line tool, but the default DEM reference url in the L2A_GIPP.xml
seems not to be valid (anymore):
Trying to retrieve DEM from URL http://data_public:GDdci@data.cgiar-csi.org/srtm/tiles/GeoTIFF/ this may take some time ... [Errno socket error] [Errno 110] Operation timed out Download error %s, flat surface will be used
This is most likely related to “In January 2021 the source for SRTM 3Sec data which are automatically downloaded by SNAP has changed” (https://senbox.atlassian.net/wiki/spaces/SNAP/pages/321126402/Collection+of+FAQs) and Snap 8 BackGeocoding in Alpine linux Docker.
I tried to replace the url by
but sen2cor seems to directly expect a .zip file:
Trying to retrieve DEM from URL http://skywatch-auxdata.s3-us-west-2.amazonaws.com/dem/SRTM90/tiff this may take some time ... File is not a zip file DEM not available, flat surface will be used
Is there an URL available that is compatible with sen2cor?
