Hello Vishnu, These flags are in the second category, so products are still provided by default even when these flags are raised. There is no need to modify anything in common.py. Even "case2" (1024) and "inconsistency" (2048) are not included in the recommended bitmask value 1023. To avoid filterin...

Dear Vishnu, There are two kind of flags: 1) Those for which the products are empty (set to NaN) - these are defined by the variable BITMASK_INVALID in params.py 2) The other flags (see common.py), for which the products are still calculated. These flags must be removed by the user, so avoiding them...

You are passing 'result' to Level1_MSI, which is not a variable but a string.

Sorry, I have not received your images.

Dear Binbin, Good to know that you are planning for a massive processing. You can activate parallel processing with the argument multiprocessing=-1 which will make the processing faster on a single computer. Then you can use a simple loop over the files, or set up a processing on a cluster, dependin...

Hi Brenner,
I suspect that the issue might be in the Level1 class, but I did not understand which Level1 class you have used: which one is it ?

Hi, Processing landsat8 requires that the solar and sensor angles are calculated beforehand. This requires applying the program "l8angles" available on https://www.usgs.gov/land-resources/nli/landsat/solar-illumination-and-sensor-viewing-angle-coefficient-files "l8angles" must be applied with the fo...
