invalid south-west-north-east settings in V2021.2 ocssw
Hi, I updated my ocssw to V2021.2 recently in Ubuntu 20.04. I found the l2gen could not process the region of interest in MODIS Aqua imagery using south-west-north-east parameters. For example, the command such as l2gen ifile= A2020366063500.L1B_LAC geofile=A2020366063500.GEO ofile=A2020366063500_l2...

how to reduce the size of files generated by l2gen
Hi Sean,
Thanks for your solutions, it is what I want to do. Because I need to generate many products from one whole granule imagery to further process using my programs so that I must consider the disk space in a big ROI.
This XML file works perfectly!:grin:
Thank you again!
