[PS3-7-1-1] Radiometrically corrected

Depending on the sensor and the provider, remotely sensed imagery is made avalilable to the user at different processing levels. For Sentinel-2, the lowest product level made available to the user is Level-1B. THe Level-1B product provides radiometrically corrected imagery in Top-Of-Atmosphere (TOA) radiance values and in sensor geometry. Radiometric corrections applied to the Level-1B are: dark signal, pixels response non uniformity, crosstalk correction, defective pixels interpolation, high spatial resolution bands restoration (deconvolution puls denoising), binning (spatial filtering) for 60m bands.
