Flags and Reprojected files
Thanks for the reply. I understand that reprojection would 'mix' pixels and can affect l2flags. But in reprojected files also l2flag array looks fine. It is the flag_percentages that are not correct in reprojected files. This is what I find in OLCI L2 files. When I checked the same in ...

Hi Sean, So just to clarify: Should I use gpt (geocrop?) to first extract domain in L1A and GEO files? Then generate L1B? I am not sure if I use lonlat2linpix to get line-pix limits for L1A how would that be communicated to modis_L1B.py. And the GEO file will stil...
