WHAT'S HERE

See below for a list of files.  Mainly this is a quick'n'dirty example
of what can be done with some existing tools, mostly by Alan Crosswell,
in terms of displaying maps generated from TIGER data.

The program (ap2.tk) is in Tcl/Tk and takes the .map filename as a
parameter.  The two .map files included are slightly different versions
of  Arapahoe County, Colorado, data.  (I chose that because I live there,
and know the area.)

Nothing particularly fancy -- clicking on a feature with the middle
button will display its name in the console window.  Major roads are
drawn wider than normal roads.  Stuff like that.

When/if I get a chance to add bells and whistles (zooming?) I'll add it,
but don't hold your breath :-)

THE FILES

The files here are:

   - this README
   - ap2.tk  -- a Tcl/Tk program to display a .map file
   - arap-label.map  -- Arapahoe County (CO) roads with town labels
   - arap-water.map  -- Arapahoe County roads showing streams and lakes

The file ap2.tk is modified from the program aprs.tk that was included
with the tig2aprs programs by Alan Crosswell, (c) 1997 and distributed
under the GNU Public License.

The files arap-label.map and arap-water.map were created using tig2aprs
on TIGER/Line files (specifically, the TGR08005 series) made available
by Bruce Perens, also under the GPL.  For brevity, the TGR files are not
included here (they're over 10 megabytes).  See http://www.perens.com
or email me (al11@delphi.com) for copies of the raw TGR files.
