Re: 20011115: NEXRAD reflectivity mosaic availability

David,

The land/water coloring is done in gpmap using the BND parameter.
Attacthed is the script (NEXRIII.csh) which uses gdplot2 and gpmap.

The individual NIDS station plot is created from a cgi I created that
calls: radmap_sw -s input_nids_file output_gif_file "${TITLE}"

The radmap_sw program must have the map and station tables
in the working directory (eg it doesn't search for them).
If you need more information on radmap, see the
$GEMPAK/source/contrib/tdl/radmap directory.

The files that must exist in the radmap working directory are:
drwxrwxrwx 9219/2000      0 Sep 18 10:57 2001 .radmap_work/
-rw-r--r-- 9219/2000  82485 Mar 20 13:58 2001 .radmap_work/cities.rad
-rw-r--r-- 9219/2000  35353 Mar 20 13:58 2001 .radmap_work/geog.tbl
-rw-r--r-- 9219/2000 1756160 Mar 20 13:58 2001 .radmap_work/hicnus.nws
-rw-r--r-- 9219/2000 1600512 Mar 20 13:58 2001 .radmap_work/hipona.nws
-rw-r--r-- 9219/2000 750592 Mar 20 13:58 2001 .radmap_work/hiponw.cia
-rw-r--r-- 9219/2000 289792 Mar 20 13:58 2001 .radmap_work/lakes.ncp
-rw-r--r-- 9219/2000  64512 Mar 20 13:58 2001 .radmap_work/loconh.gsf
-rw-r--r-- 9219/2000 221184 Mar 20 13:58 2001 .radmap_work/mepowo.gsf
-rw-r--r-- 9219/2000   6831 Mar 20 13:58 2001 .radmap_work/nidprd.tbl

You can find those files wither in the directory mentioned above,
or the standard $GEMTBL directories.

The tdl program is just a hardcoded version of gpmap which they created to
eliminate some of the time it takes to search for the files. Just makes
getting the output to the web faster.

If you need more info, I'll be back after the 28th. Kind of in a hurry now.
