Hi all, I'm using i.atcorr for atmospheric correction of Pleiades imagery. The data comes as DN in 12 bits. Reading the manual of i.atcorr, I get that I must provide radiance data. Hence I converted each band to radiance using gain and bias from the metadata. Now, for the range parameter in i.atcorr, I assume I must pass the min/max output of r.info for each band. There's no extra info in the metadata about theoretical range for each band.
In the i.atcorr manual and in some older emails, I read for example, that the range for Sentinel 2 is 1 to 10000. However here [1] it says: "Per-pixel radiometric measurements are provided in Top Of Atmosphere (TOA) reflectances along with the parameters to transform them into radiances". AFAIU, 1,10000 is TOA range. So, I'm a bit lost... What is really this range parameter representing? Thanks much in advance Vero [1] https://earth.esa.int/web/sentinel/user-guides/sentinel-2-msi/product-types/level-1c
