Hello!
I am trying to export a mosaic of 2 S2 L2A images. The workflow I use is as follow :
Resampling both image to 10 meters using Raster - Geometric - Resampling. I then use both resampled image to create a mosaic using Mosaicking (I specify my desired CRS and put the pixel size to 10 meters). Finally I export to Geotiff / BigTiff.
My problem is that the resulting tiff have values for each band that seems normalized or corrected (values between 0 and 1). I need the raw value from the pixel (on the 10 000 scale). I have outputted other L2A images (no mosaicking) without problem, that is why I suspect the mosaicking as the problem, but I tried many variances and cannot find how to do it. Is it because such rescaling is necessary to perform a good quality mosaic? Would there be a way to restore or extrapolate the raw values after the mosaic?
Any insights are welcome
Thank you!
