Re: SeaDAS Spectrum View

Please see the attached image of the bands from the SeaDAS File Manager. I want to group Rrs from the two groups shown in columns 3 and 4 and plot spectra on the same plot.
Thank you for your help.

Re: SeaDAS Spectrum View

Hi Danny,
Thanks for your previous email, which was a while ago!
I have a question about grouping bands. If I am using a file with two collocated images, I have two sets of Rrs. How do I group them in different 'band groups'? I don't see a way to highlight and select bands.
Thank you.

Hello, I tried running OLI Collection-1 data. On my Mac, with a GUI I can run l2gen and process OLI images. But even with Collection-1, on adapt/container I get the same messages as before! When I typed 'seadas_info', strangely I get this message '/usr/bin/env: python3 : No such file or directory. B...
