Re: SeaDAS Spectrum View
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...

Re: Seadas GEO.hdf
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...

Re: SeaDAS MODIS Cloud Mask
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 ...

Re: Project Terra MODIS L1B Swath to L3 500m Sin Grid
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...

Re: process derived products with SeaDAS
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
Input: L2 file > program: l2bin > Output: L3 bin file
Input:L3 bin file > program: l3mapgen > Output: L3 mapped file

Re: Selecting reflectance math band
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) > ...

Re: Output setting of batch processing changes
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 ...

Re: I wonder the meaning of reference pixel
The default settings of the Reproject Tool are fine if you wish to reproject the source scene while retaining it's original boundaries and resolution. However, if you wish to have the Reproject Tool crop your scene into a specified region and/or adjust the resolution, then modifying the "Output...

Re: Output setting of batch processing changes
In order for us to replicate what you are seeing, can you provide the file myGraph3.xml which you are loading into the Batch Processing tool (or can you upload the file's full contents)?

Re: contours of bathymetry required
You can add contours in SeaDAS as described in the previous post. Note that you can only make contours on the selected band. So since you want contours of Bathymetry overlaid on chlor_a, you will need to: 1. Load VIIRS file. 2. Create bathymetry (which creates a band called "bathymetry" 3....
