[gdal-dev] Representing a grib file as a netCDF

[Zachary Flamig]

Hey Norman,

Interesting idea. I think it will be a little bit tricky because it is hard to uniquely label each band in a grib file.

I actually use a modified version of gdal_translate where I can specify the GRIB_ELEMENT, GRIB_SHORTNAME, and GRIB_FORECAST seconds that I want to match to extract specific bands. This lets me process similar grib files without having to map band numbers explicitly. I probably didn’t do this the best way, maybe it could use an SQL format like -where uses.

Just some quick thoughts,
Zac
