Hi all,
I'm running into issues processing an SLC scene. Both GTC and RTC results are not really usable. I suspect my DEM is the problem and I'm wondering why, because I'm using the same DEM to successfully create an RTC product with SNAP. Here is the gdalinfo output if you're interested.

Can you provide some guidelines on format requirements for the DEM? Or at least a reproducible example in the notebook section. download_data.sh could, for example, be extended by a section that downloads DEM tiles from an open source (e.g., here) and prepares it with GDAL in the way sarsen expects.

Cheers, Marco
