20030122: Plot Point on CIP Map

Greg,

To use GPANOT in your script, you would run the program after your 
gplot2 invocation and befor the gpend command you have, such as:

#!/bin/csh

gdplot2 << EOF
   ...
   stuff
   ....
   r

   e
EOF

gpanot << EOF2
 GDFILE   =  
 SATFIL   =  
 RADFIL   =  
 GAREA    = 22.5;-117;46.5;-64
 PROJ     = STR/90;-100;0/NM
 DEVICE   = gif|cip4.gif|1024;768
 PANEL    = 0
 CLEAR    = n
 SHAPE    = marker
 INFO     = 5/2.7
 LOCI     = #40;-105
 LINE     = 2
 CTYPE    =

EOF2

gpend



In the above GPANOT, note that CLEAR has been set to no, so that you
will overlay your gdplot2 image. The values for SHAPE, INFO, LOCI, and LINE
specify to draw a marker (SHAPE) using marker number 5 and size 2.7
(INFO), to plot at lat;lon = 40.0N, 105.0W (LOCI) and color 2 (LINE).

If you use the "phelp shape" command, you will see the instructions for
the possible markers, symbols, text, lines, etc that you can use to annotate
your plot.

>3) Use NMAP2 product generation to create a vgf file of your markers 
>and annotations (particularly useful if you have other labels, fronts,
>symbols etc to mark as well). Then, after saving the vgf filem use GPMAP
>to plot the vgf file as an overlay on your GDPLOT2 map.
