Hello,

I'm just starting to explore the possibilities of ocssw.
Tell me, it's possible to generate a NDVI/EVI dataset from MODIS l1b data using a set of ocssw modules.

Regards,
Dmitry

Dmitry,

Yes, the l2gen code can produce NDVI and EVI products.

Sean,

I see a lot of arguments, but I can't figure out what I should pass to get ndvi. Could you poke me in the documentation section or just write what the command should look like.

Dmitry

Here is the help for l2gen https://seadas.gsfc.nasa.gov/help-8.2.0/processors/ProcessL2gen.html

If you do l2gen on GUI, you can add ndvi and evi in the "Selected Products" section on the Products tab

If you prefer to run l2gen on command line, you can try this --
Note that you need a geo file in the same directory with your L1B file

Many thanks,

Please, where can I find the full list of MODIS (L2) products that I can generate with l2gen.

Dmitry

There is a products.xml in your ocssw/share/common that has detailed information about the products that l2gen can generate.

Or you can do or

Many thanks.

Dmitry
