Neil,

I provided the web page:
http://www.unidata.ucar.edu/packages/gempak/examples/gdradr/

There is an example of combining the radar grid with the RUC grids
to create precipitation type masks:
http://www.unidata.ucar.edu/packages/gempak/examples/gdradr/NEXTYPE

I also mentioned that the nts restore products used in NMAP2 are
in the $NMAP_RESTORE/radar/nexr/ directory.
The restore file will show the settings that you would use in gdplot2
to produce the plot. That should be a good guage for your script.
In gdplot2 you can use the restore file and just update
the fields like PROJ, GAREA and DEVICE for your plot.

Let me know if you need more info.
