Bob, There is a $GEMMAPS/cwa.nws map file already. Garp has this map defined down at the very bottom of the list of maps just below the RFC areas. You just have to toggle it on for display. You can specify map overlays in the GEMPAK programs as well by specifying the map files in the $mapfil parameter like: $MAPFIL = cwa.nws+hicnus.gsf+hipowo.cia map=8/1/1+5/1/1+6/1/2 Is this the map that is requested, or do you mean the individual zone/counties refered to be the FIPS/UGC code such as at: http://www.nws.noaa.gov/modernize/shapemap/zones/c11.htm Steve Chiswell Unidata User Support On Tue, 8 Feb 2000, Bob Rozumalski wrote: > > > Steve; > > One of the offices would like an overlay of their warning area > when viewing data in GARP/NAWIPS.
