Question: Spectra in SeaDAS GUI
Replies: 4

Re: Spectra in SeaDAS GUI

When you draw a vector box layer on a SeaDAS loaded image it creates an associated mask. This mask by default will be called "geometry". To do statistics on this "geometry" region of interest, use the Statistic Tool (Menu > Analysis > Statistics) Check the "Use ROI Mask"...

Question: Transferred mask goes in folder Bands - SeaDAS 8.1.0

Re: Transferred mask goes in folder Bands - SeaDAS 8.1.0

One additional thought. The xml file export is for masks of type "MATH" and not of type "GEOMETRY". If you are trying to import a mask based on geometric coordinates then you can do this with a ESRI shapefile. For a given scene file, to export a vector as a shape file, in File Ma...

Re: Transferred mask goes in folder Bands - SeaDAS 8.1.0

Hi Oliver, I just tested this in SeaDAS 8.1.0 and it works fine. I can export a mask from one file and then import it into another file. In my test, the mask in the 2nd file gets loaded correctly into the masks folder and not the bands folders as you mentioned. So I cannot replicate your bug. Can yo...

Re: I have problem about extracting multiple NetCDF files with multiple stations of interest

There's a tool called Pixel Extraction in SeaDAS. I think it's a bit hidden, but you can find it by typing "Extract Pixel Values" in the search area of the SeaDAS GUI (top right corner of SeaDAS). The Pixel Extraction tool let's you enter the input files, and specify the coordinates for yo...

Question: Correlative plot
Replies: 5

Re: Correlative plot

The Correlative Plot tool has a ROI mask checkbox. So you use this to specify your ROI mask(s). Note that this is ROI (region of interest) and not a flag masking selection. The best approach would be to create a new quality mask via the Mask Manager, which is to be treated as a ROI mask. You can the...

Question: SeaDAS 8.1.0 installation error

Re: SeaDAS 8.1.0 installation error

Mike, I'm able to install on my Big Sur (11.6) - which is using java (build 1.8.0_241-b07). But you should not need to install JDK because SeaDAS comes packaged with a JDK which it uses. What happened during installation? Did you get an Installer GUI? What steps did you click within the installer GU...

Question: How do I access data via OPeNDAP in SeaDAS 8.1.0?

Re: How do I access data via OPeNDAP in SeaDAS 8.1.0?

Both SeaDAS 8 and SNAP do not support OPeNDAP. There are no current plans (at least in the near future) of adding OPeNDAP support to SeaDAS 8 or SNAP. SeaDAS 7 does support OPeNDAP.

Re: Problem with new version of SeaDAS/OCSSW

Hi Amita,

You will need to have SeaDAS OCSSW installed in a directory in which you have read/write permissions as some SeaDAS OCSSW programs read/write to these directories.

Re: How to Get Reflectance Data for Lat/Lon?

There are a lot of gpt help pages other than the one you listed, either on the SeaDAS web page or in the SeaDAS application itself: See https://seadas.gsfc.nasa.gov/help/ For instance the GPT Cookbook: https://seadas.gsfc.nasa.gov/help-8.1.0/GptCookbook/gptCookbook.html Also since gpt is a tool in S...

Re: How to Get Reflectance Data for Lat/Lon?

SeaDAS (as of 8.1.0) does not yet support gpt command line operations, but gpt is planned for the next SeaDAS release. However, you can do command line operations currently with the SeaDAS science processing (OCSSW) tools such as l2gen, l2bin, l2mapgen, etc. If you wish to explore the gpt tools now ...
