As far as I know is a raster.
You can get it from:
http://www.qlands.com/other_files/2011-01.grib
This grib is only one record from the whole file and it contains maximum
temperature for the whole world.
The following is the wgrib ./2011-01.grib -V of the file

is it raster or vector data?
can you make the file accessible some place?

Hi,
I am trying to open a grib file (meteorological data) with GDAL 1.8.1
but i get the following error:
./2011.grib is a grib file, but no raster dataset was successfully
identified.
gdalinfo failed - unable to open './2011.grib'
Other tools like wgrib successfully opens the same file.
Any idea what is wrong?
Thanks,
Carlos.
