Thanks for the information Guillaume, it seems that the packaging has changed on anaconda.

Hi Guillaume,
Indeed we are currently having a technical problem here, and download.hygeos.com is not available for the moment. Hopefully it will be fixed today.

Dear Julia,

It seems you are passing a list to Level1_MSI instead of a filename (str).
A simple loop on many granules may look like this in python:

Code: Select all

from pathlib import Path
for filename in Path('/path/to/directory/').glob('**/GRANULE/*'):
    run_atm_corr(Level1_MSI(str(filename)), ...)

These options are for processing a rectangular part of the image, from line sline to eline and column scol to ecol.

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...
