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)?

Question: contours of bathymetry required

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....

Question: Mismatch between input geographic limits and output of l2gen for MODISA using V2022.0

Re: Mismatch between input geographic limits and output of l2gen for MODISA using V2022.0

Hi bijaylaxmi, l2gen can subset the standard resolutions, however for the case of MODIS with the extra resolution options, the 250m and 500m resolution options does not currently subset correctly to the requested geographic boundaries. For MODIS at 1km resolution, the l2gen subset option works fine....

Question: Seadas T2022.2 modis_atteph and getanc issues

Re: Seadas T2022.2 modis_atteph and getanc issues

There is a sea ice concentration band contained within the SST ancillary file, so this replaces the NSIDC file. Going forward, the program getanc will return the SST file for both the sstfile and icefile parameters and will not return the NSIDC file for the icefile parameter.

Re: Mismatch between input geographic limits and output of l2gen for MODISA using V2022.0

Please post the exact file name you are using. Also if possible post your par file ... or cut and paste the subsetting options which you used. For example I just ran l2gen on file: AQUA_MODIS.20101010T180500.L1B.hdf # SUBSETTING OPTIONS north=40 south=35 east=-70 west=-75 The resultant file had the ...

Question: l2gen processing

Re: l2gen processing

When you choose a suite in l2gen it applies the values in the particular suite parameter file. So for example for modis the suite files are: IOP: $OCSSWROOT/share/modis/msl12_defaults_IOP.par GSM: $OCSSWROOT/share/modis/msl12_defaults_GSM.par OC: $OCSSWROOT/share/modis/msl12_defaults_OC.par etc. You...

Re: Sentinel-2 MSI

This doesn't fully answer your question, but striping can be band/detector specific. You are showing Rrs_443 whereas the true color image you mentioned uses the 490nm, 560nm, and 665nm bands.

Question: Spectra in SeaDAS GUI

Re: Spectra in SeaDAS GUI

The Spectrum Plot is for single pixels. You can place pins and run it for all the pins and you will get a spectral line associated with each pin. So one line per pixel. If you don't use pins then it monitors the pixel directly beneath the cursor. So unfortunately it doesn't do what you want regardin...

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"...
