Hello, Sean. I can now confirm that there is an issue with this code.

l2gen on landsat 8 collection 2

Hello, I've encountered some issues recently while processing Landsat 8 Collection 2 data using the source code. It seems like Landsat 8 band 9 is not being read? While examining the l1_oli.c code, I noticed that band 9 is not being read during the band reading process. It's also possible that my un...

OCSSW source code

Hello, I would like to ask why I am unable to successfully download the source code of ocssw now, even though I entered my own account password when executing the command.
