Sen2cor: pixel values

Optical Toolbox sen2cor
#1

Hello everyone,

I preprocessed a sentinel-2 image using sen2cor. However, resulting pixel values are integers. For example, for some bands pixel values range from 0 to 9124. Am I on the right track? I was expecting float values.

Thanks in advance for your reply,

Hi,

in the sentinel-2 products the pixel values are stored as integers, to transform them into reflectance you have to divide them by 10000. If you open the full product by opening the metadata file in SNAP, this conversion should be done automatically.
Is it possible that you have opened the jp2 files individually? In this case, the values are read directly from the image (without conversion)
