to just download the unextracted VIIRS files and do the extractions
yourself on your own machine.

L2gen L1 Landsat 8 Processing for Inland Lake

One more short post script:

When working with Landsat 8 data, I have found that I can often make
a decent radiometric land mask for the scene in question by fiddling
with the contrast of the rhos_865 product from l2gen.

Hi Amanda,The l2gen program does not change the projection of the Landsat 8 scenes duringprocessing.  The output pixels have the same universal transverse Mercatorcoordinates as the corresponding input pixels.  In addition, l2gen stores thelatitudes and longitudes of each pixel in separate...

Hi Daniele,
