Re: SeaDAS Spectrum View

Hello, I know where the 'spectrum view' is. The problem I have is with the filtering option! It is not the same as it was in the previous version!

S2A_Rrs_443.png Hello, I am processing Sentinel-2 MSI Level-2 data from Level-1 using l2gen. I see striping in Rrs in this image (attached) while the true-color image from Copernicus site does not show any striping. Not all images I process have striping.

Re: Landsat OLI processing

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!

Re: Landsat OLI processing

Hello,
Thank you for your replies.
I am not using GUI but command line version on a linux machine. I guess it must be the Collection 2 data!
About SeaDAS version on adapt I have two versions -- but SeaDAS-8 has issues so I am using 7.5.3!
Thanks.
