Quick update:
Could this be an issue related to the blocks outside of the AOI? Those are all assigned the value 1. Areas that are within the blocks that are processed but masked out carry the value -32767. See attached image - apologies for the terrible drawing :)

Hi stee,

yes, I guess the nodata is inherited from the input data (QAI) on construction of the internal image struct.
I think I am actively writing -32767 if there is nodata, but
if a block is completely skipped, nothing is written in there, and when writing, GDAL fills with the nodata from the metadata.
I will need to explicitly set nodata. Then, I guess the problem will be gone. Still, I didn't find time to do so yet.

Cheers,
David

This is now fixed with a7d3de5 in the develop branch for the CSO submodule.

Please try again!

I did a quick check just now and the results look good.

Thanks David!
