<font face="courier new,monospace">I have been working quite a bit with the netcdf driver and weather data. I am noticing that many CF-1.0 (NetCDF Climate and Forecast Metadata Convention) tags are not supported or referenced in the driver. In many cases this forces some data to be set to a default. I am mostly working in the spatial reference tags and this is causing problems as I don't know where my grids are in space.<br>
<br>From the NetCDF format page:<br></font><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote"><h2 style="font-family: courier new,monospace; font-weight: normal;">
<font size="2">Georeference</font></h2><span style="font-family: courier new,monospace;">
There is no universal way of storing georeferencing in netCDF files.
The driver first tries to follow the CF-1 Convention from UNIDATA looking for
the Metadata named "grid_mapping".
If "grid_mapping" is not present, the driver will try to find an
lat/lon grid array to set geotransform array. The NetCDF driver verifies
that the Lat/Lon array is equally space.</span><p style="font-family: courier new,monospace;">
If those 2 mehtods fail, NetCDF driver will try to read the following
metadata directly and set up georefenrencing.
</p><ul style="font-family: courier new,monospace;"><li>spatial_ref (Well Known Text)
</li></ul><ul style="font-family: courier new,monospace;"><li>GeoTransform (GeoTransform array)
</li></ul><span style="font-family: courier new,monospace;">
or,
</span><ul style="font-family: courier new,monospace;"><li>Northernmost_Northing
</li><li>Southernmost_Northing
</li><li>Easternmost_Easting
</li><li>Westernmost_Easting
</li></ul></blockquote>
