Re: SEADAS pixel extraction

Yes you can import county/state boundaries and you can also export pixels for a particular region. To import county/state boundaries you will need to find an ESRI shapefile from an external source which contains the geographic boundaries. For instance this site contains a shapefile of all the counti...

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

Question: Density slice

Re: Density slice

SeaDAS does not have a Density Slice tool. You can adjust the Min/Max values within the Color Manipulation Tool, which would have the effect of creating a single "color slice". If you wish to have multiple views ("slices") of a single band using differing Min/Max color settings, ...

Re: SeaDAS Spectrum View

Can you post a screenshot of the File Manager GUI, it's bands in the folder, so we can know what you are trying to group? Also explain what your desired grouping is.

The problem with your last plot is likely that you don't have your bands grouped together into folders in the File Manager. See the two attached images. The bands ...
