Hi Brice, The image linked to in the support message, http://www.srh.noaa.gov/ridge2/Conus/RadarImg/NAT_N0Q_0.gif can be created using either of the GEMPAK programs "nex2gini" (output to GINI) or "nex2img" (output to GIF). These programs build a gridded composite of level3 products and save to image format. GINI images can be output to GIF with GEMPAK graphics programs such as "gpnids" and "gpmap". Before you start creating national composites on your own, you could use the LDM to request the FNEXRAD feed from the Unidata IDD, which contains national composite GINI images for 7 products (DHR,DVL,EET,HHC,N0R,NTP,N1P), created every 5 minutes. Information on the FNEXRAD data feed, LDM pattern actions and available products can be found at http://www.unidata.ucar.edu/data/radar.html#fnexrad If you help me understand better the scope of your project (how you intend to script, use crontab or use an LDM "EXEC" command on incoming files) I can offer more advice. -Michael James Unidata User Support > Tom, > > Bryan pointed this out to me - > > http://www.unidata.ucar.edu/support/help/MailArchives/mcidas/msg04493.html > > I am being tasked to do something similar.
