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.

Spectra in SeaDAS GUI

Hello,
I am using SeaDAS GUI for some analysis. I have collocated two images, resulting in two sets of band reflectance (for reference or master image and the other collocated with it. If I draw a box on a region, is it possible to get average spectra for this box?
Thank you for your help.
