support<BR><BR></FONT></DIV>
<DIV>GDAL now supports netcdf format using CF convention as specified by
unidata.<BR><BR> <A
href="http://my.unidata.ucar.edu/content/software/netcdf/conventions.hdf">http://my.unidata.ucar.edu/content/software/netcdf/conventions.hdf</A><BR><BR>The
software looks if the variables lat/latitude and lon/longitude are presents in
the netcdf file. If found, these variables are used to specify the
georeferencing transformation.<BR><BR>I'd like the community to try it out and
if there are some problems, let me know. GDAL netcdf format also works on
Windows with he precompile library version 3.6.1-beta1 (January
2005).<BR><BR>Regards,<BR>Denis Nadeau<BR><SPAN class=111044315-18082005><FONT

files directly from disk. I compiled the c netcdf libraries
from unidata, then gdal, then mapserver, all worked
fine.</FONT></SPAN></DIV>

<DIV><SPAN class=111044315-18082005><FONT face=Arial color=#0000ff size=2>I am
finding that gdal isn't picking up any geographic coordinate information from
the netcdf files, despite them having a geogrid, I am putting this in by
hand in the map file.</FONT></SPAN></DIV>

WCS getCoverage query worked, returning what was a netCDF file on disk as
a floating point geotiff. </FONT></SPAN></DIV>

is really good, thanks, once I have got fully working on
the production system, I will update the howto on the MapServer web site
