Re: Failure to install install_ocssw.py in MacBook Air (M2, 2022)

Make sure you are using the latest ocssw installer. Download it according to the instructions on this page: https://seadas.gsfc.nasa.gov/downloads/ Your file should be "install_ocssw" and not "install_ocssw.py" so my guess is you have an older installer file. Also you don't run t...

Re: L2Gen ifile warning

Please show the full file name so we can know whether it is a file from a mission supported by SeaDAS. I'm guessing it is Landsat (8 or 9) OLI. You can determine whether a mission file is valid using the "obpg_file_type" command at the command line: For example: obpg_file_type LC08_L1TP_01...

Question: how can i export mask pixel in seadas 8.2?

Re: how can i export mask pixel in seadas 8.2?

This appears to be a bug in this particular tool specific for level3 files. A workaround seems to be that after you have created the masks in your level-3 file then you can save the file by right clicking on the file name and selecting "Save Product". This will convert your file into a BEA...
