Scene Classification Algorithm Sentinel-2


I found on the ESA website a scene classification/segmentation algorithm:

and I am trying to replicate it (with a python script). So far I have been unable to replicate it since some steps don’t indicate the value of the thresholds.
For example step 1a says band 4 T1 threshold and band 4 T2 threshold are 0.07 and 0.25 respectvely. But the next step 1b doesn’t mention the values of NDSI T1 and NDSI T2. Other steps that are missing thresholds are for example step 3 and step 5.2 among others.

Could you provide a link or some indications about where to find these threshold values so to be able to replicate the segmentation algorithm?



you will find them in the Sen2Cor ATBD:

Thanks a lot :slight_smile:
