<p class=MsoNormal>Greetings,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>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;
<a href="http://www.weather.gov/om/tpb/490body.htm">http://www.weather.gov/om/tpb/490body.htm</a>)
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? <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>On last try, I have been using:<o:p></o:p></p>

<p class=MsoNormal>gdal_translate -scale 988 1360 1 256 -ot Byte -a_srs
