        Does that tool process HDF-EOS swaths (e. g., MODIS Level 2 or
        AIRS Level 2), or does it require MODIS grid data (e. g., MODIS
        Level 3)?  Which products you've tried the tool on?

        Reprojecting and subsetting of HDF-EOS grid data is, indeed,
        straight-forward, and usually could be done with, e. g.,
        gdalwarp(1).  Not so for the swath data.
