I compared jpg2000 file of a band and the corresponded band (for the same granule, clearly) into xml file.
I noticed that the spectral range (max, min) is completely different. Values for each pixels are different (coincidently for some pixels jpg have half value of xml file). Please, can you help me to understand? Are both of them (jpg 2000 and xml) TOA reflectances values? Is the QUANTIFICATION_VALUE = 10000 for both of them? May be this problem a matter of compression for jpg?
Thanks and apoligize if answers are yet into the forum.
