polar2grid is a software package, mainly python, for converting polar orbitting satellite data from various sources (VIIRS, MODIS, etc.) into formats that are useable by meteorlogical visualization applications, such as AWIPS, NINJO, etc.
Currently, polar2grid only works on converting a few VIIRS bands to AWIPS-compatible NetCDF files.
The original repository included a "vendor" directory in the root repository that was being used to store the vendor release of ms2gt. The repository was converted to git using "svn2git" which does not support this structure. For now, the "vendor" directory is not included in the git repository although it may be added later.
