[GRASS-dev] success with NetCDF

[Michael Barton]

I was able to directly import our test NetCDF file into GRASS using r.in.gdal.

The trick is to properly specify the file and data subset name. Here is the command version, though I did it through the GUI too.

r.in.gdal -o -e input=NETCDF:"/Users/cmbarton/Desktop/ppt_SRESA2_mid_annual_down_anomaly.nc":ppt output=netcdftest band=1 title=globalppt

I'm not sure that the -o and -e flags are needed. Note the way I specified the input. It has a NETCDF prefix, the file name (in quotes), and the relevant variable name--all separated by colons (:). I had to get this info using gdalinfo first. My guess is that you can directly import multiple bands this way and not just one at at time.
