SLC preprocessing uses SRTM instead of Copernicus DEM #60
Description
At the moment the Update Geo Reference SNAP function (which we use for generating the terrain corrected lat/lon grid) does not allow to auto-download the Copernicus DEM. Therefore at the moment all the SLC preprocessing workflow uses the SRTM DEM for consistency.
To solve the issue we could download the Copernicus DEM and give it as "External DEM" as input of Update Geo Reference
