Greetings,
I have a netcdf file of NCEP model data (originally in GRIB) that I'm converting over to a GeoTiff. I'm trying to set up the exact projection for the AWIPS Lambert conformal grid (#252 - RUC-20km; http://www.weather.gov/om/tpb/490body.htm) but the data is off center from what the original GRIB file displays using GEMPAK. I think the problem lies in the fact that the lower left and upper right corners exactly mirror those of the other corners, which isn't what should happen with LCC. Could someone please help me with the exact specification of the gdal_translate command line? On last try, I have been using: gdal_translate -scale 988 1360 1 256 -ot Byte -a_srs '+proj=lcc +lat_0=39 +lat_1=25 lat_2=25 +lon_0=-95 +datum=GRS80' -a_ullr -139.86 54.17 -69.04 17.34 NETCDF:"lccmod.nc":HGT_875mb lccmod-final.tif Thanks, Chris Dr. Christopher J.
