[gdal-dev] question about reading grib2 file

[Matt Funk]

One more comment,

when i use the wgrib2 with the -spread flag i get lat/lon/elevation.
When i use the -text flag instead i only get the elevation (which is the
same data i get through python/gdal).

One thing that did occur to me is that it is possible that the wgrib2
utility computes the lat/lon when given the -spread flag.
Anyway, maybe this is not a gdal issue after all.

thanks
matt
