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?

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 ...

Question: Exporting Ocean Color Chlorophyll data

Re: Exporting Ocean Color Chlorophyll data

This may help. In SeaDAS, there is a pixel extraction tool. Menu > Raster > Extract > Extract Pixel Values. This tool extracts pixels from a raster grid around a placed pin in the GUI view window (or a set of pins). You can adjust the extraction grid size as well as set flags. This tool will extract...

Re: data processing # HAWKEYE

The L2 Hawkeye file might be large. You could try increasing your virtual memory available to SeaDAS 7 GPT.

Find the file:
[SEADAS_APP_HOME]/bin/gpt.sh (or gpt.command or gpt.exe)

Try changing the line:
-Xmx1024M \

to:
-Xmx2048M \

or perhaps:
-Xmx4096M \

Question: Colorbar
Replies: 2

Re: Colorbar

Your image does not contain enough pixels and this is why the color bar is blurry. You need to export the scene and the color bar as separate files. You can then assemble them together in PowerPoint or some other software if you wish to display them without resolution issues.

Question: Colorbar

Re: Colorbar

You are probably talking about the color bar layer. The color bar is a raster image layer placed on top of a raster image of the scene. If the number of pixels in your cropped image is small, then the color bar will be blurry because of the low resolution. You can export the color bar as a file, in ...

Re: color bar in seadas 8.0 beta version

We are currently developing the color bar tool for SeaDAS 8.x. It will be similar to the color bar tool in SeaDAS 7.x, but a bit better. In the meantime, you may wish to use SeaDAS 7.5.3 for exporting your color bar.

Re: OLCI data peocessing

Hi Amita, You would need to tell us a lot more for us to understand what you are doing. Judging by the faint semi-transparent compass pattern at the top left of your image it looks like you are doing a screenshot of bands viewed within the GUI. I do see a dashed line. Based on the Chesapeake Bay sce...
