Can't Add bathymetry and elevation bands and masks

Your statement "In contour, It gives line for a range of chl-a value" is incorrect, unless I don't correctly understand your meaning.  A contour line is set to a specific value and not a range of values.  The GUI does have a range component, but this is a merely a user conven...

Yes, you are right, the modis_GEO step I mentioned does need to occur before the modis_L1B step.I noticed that you are using climatology default for your ancillary.  In order to get better atmospheric correction data specific to your scene and time you should be running "Get_Ancillary"...

L1B problems

I can confirm this as a problem with loading L1B VIIRS files in SeaDAS.  In order for the SpectrumView tool which you mentioned to work, bands must have the Spectral Wavelength set.  The VIIRS file reader utility inside of the SeaDAS GUI is currently using a default generic function which ...

Question: SeaDAS displays L3B images ?
Replies: 2

SeaDAS displays L3B images ?

SeaDAS is not designed (at least currently) to display the binned files (L3b).

You can however, process these files using SeaDAS (see the tools l3bin, l3mapgen)

Landsat8 l2_flags

I do not quite understand this question.  If you post the l2gen par file (or full param list) of what you used when processing this it would help us determine exactly how you processed this.  Are you saying that pixels over land are not being identified as LAND in the MaskManager?  Da...

l2_flags viewer

Hi Ryan,

As mentioned, flags would lose their original meaning if they are reprojected.  Note: you can mask out undesired data by applying the level-2 flags during the Mosaic step.
