: : There are hundreds of maps of various kind available over
: : the net from US Geological Survey and other government offices.

: : Many of the available topo maps cover the trout waters of
: : North Georgia. The problem is, you need GIS mapping software
: : to load, read and print them. I have friends who use
: : high-end (read high dollar) GIS programs for State business.
: : I understand that there are shareware or low-end programs available,
: : but cannot seem to locate a source for them. Anyone
: : know of a source for cheap GIS software?

: : Any help would be appreciated. Thanks...

: Ley -- Use your browser to find the USGS Mapping Information Home Page.
: From there, you'll find links to an FTP site which has public domain maps
: and freeware viewers. I've downloaded some but have not yet been able to
: figure out how to make them work. Also, the University of Arkansas has a
: map generation program which apparently will allow you to program in the
: state, quad, features, etc and will generate an appropriate map on the spot
: which can then be printed. I've been struggling with this for sometime now
: and still haven't come up with snything really satisfactory. It seems that
: USGS has partnered with some commerical companies to produce the common
: topographic maps and you have to order them and pay a hefty per map fee.
: It looks like the days of the $3.00 topo are gone forever. Both sites should
: provide links to other mapping data bases. If you find something that works
: please post it here.

Ley -- Here are the addresses of the two sites mentioned plus a coupe of more. I checked the
University of Arkansas site and it appears only to have maps of Arkansas. The map generators is
very interesting and worth a visit. The University of Virginia site does have maps of the U.S. but
they seem to be fairly large scale and limited onfeatures. The last site is at the University of
Texas and it provides a large number of links to other map sites.

The sites are:

USGS -- http://www-nmd.usgs.gov/
University of Arkansas -- http://www.cast.uark.edu/local/mapper
University of Virginia -- http://viva.lib.virginia.edu/gic/index.html
University of Texas -- http://www.lib.utexas.edu/Libs/pcl/map_collection/map_sites.html

Hope this helps.
