Hello. I'm trying to use GDAL to convert my netcdf file into a GTiff
so it can be read into GRASS. I tried using "gdal_translate -of GTiff
-b 1 NETCDF:FILE.nc:Outfile Outfile.tiff"
You probably need to specify a coordinate system, too. Do this with the
-a_srs option.
See http://www.gdal.org/gdal_utilities.html for details. The easiest
way is using the epsg codes. On my system, I can find them by:
cat /usr/share/proj/epsg | grep -i lambert -A 1
There is also a list at (http://www.epsg-registry.org/) - look under
Projected CRS type. Choose the one that you need, and amend your code.
e.g.
gdal_translate -of GTiff -a_srs epsg:12345 -b 1 NETCDF:FILE.nc:Outfile
Outfile.tiff
You might also need to warp your map into the new projection
gdalwarp -t_srs epsg 12345 Outfile.tiff Outfile_warped.tiff
See the first parts of this tutorial for details

Hope that helps,
