Hi Don: Yes, you can use NcML, though you wont be able to able to apply it to more than one file if the files have a different projection. More general would be to write a CoordSysBuilder that could look at the gloabal attributes and add the correct coordinates. An example that is similar is ucar.nc2.dataset.conv.IFPSConvention (and other classes in ucar.nc2.dataset.conv) John > I have some HDF files from a NESDIS archive that I'm trying to geolocate > and display in the IDV.
