For image aggregation you can either use the SeaDAS-OCSSW processors (l2bin, l3mapgen), or you can use the general tool: Mosaic Tool (SeaDAS > Menu > Raster > Geometric Operations > Mosaicking) There isn't a lot of OCSSW tutorials at the moment but this may help: https://seadas.gsfc.nasa.gov/help-8....

I don't believe the problem you are experiencing is associated with any difference between SeaDAS 8.2.0 and the prior SeaDAS 7 versions. 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 ...

Here's a help page showing the algorithm methodology used in SeaDAS for reprojection

I think what you are asking about is the location of the Spectrum View tool. For SeaDAS this tool is located in the Analysis toolbar, or can be found in Menu > Optical > Spectrum View. Another way to find a tool is to type the tool name in the search field at the top right of SeaDAS 8 For any file w...

For the answer to your first question: Your csv file used to import the lat/lon values into the Pixel Extraction Tool needs to be a very precisely formatted text file. For example your csv file could be as follows (where "\t" denotes a tab character, and there are no other hidden character...

The files you mention are not NASA OBPG files, but the following approach should be somewhat similar on your files. Using NASA OBPG files, a way to transfer the cloud mask from a L2 file into a L1B scene (of the same scene, same instrument, and same resolution) would be to open both the L2 file and ...

You can use the SeaDAS software to reproject NASA OBPG MODIS L1B files to the projection of a mapped image file. Use the SeaDAS Reproject Tool with the MODIS L1B file as the input (source) file and choose "Use CRS of" to specify the mapped file which contains your desired (coordinate refer...

You can process any SeaDAS Level-2 file to a mapped SMI image file using l2bin followed by l3mapgen.

Input: L2 file > program: l2bin > Output: L3 bin file
Input:L3 bin file > program: l3mapgen > Output: L3 mapped file

The BandMath expression to replicate the Chl GlobColour equation 6 of the paper you reference would be: First create band named R: if (log10(Rrs_443/Rrs_555) > log10(Rrs_490/Rrs_555) and log10(Rrs_443/Rrs_555) > log10(Rrs_510/Rrs_555)) then log10(Rrs_443/Rrs_555) else ( if (log10(Rrs_490/Rrs_555) > ...

The bad news here is that I can confirm when I load into either the GUI Graph Builder or the GUI Batch Processing an xml file for the Reproject operator containing the fields of the Reproject "Output Parameters", these particular parameters are NOT loaded in, and the defaults are used. We ...
