10.7 Other Applications

Linux is a playground for geographic information, and there are a lot
of other applications out there for you to play with.
GPStrans
(http://sourceforge.net/projects/gpstrans) and
GARNIX (http://homepage.ntlworld.com/anton.helm/garnixl)
are free applications that exchange information (track, route,
waypoint, etc.) with a Garmin GPS. If you want to enjoy the
increased accuracy of Differential GPS without having to buy a DGPS
radio, see the DGPS over the Internet project at
http://www.wsrcc.com/wolfgang/gps/dgps-ipl.

If you're looking for a public map server with U.S.
street maps, the U.S. Census Bureau makes street maps that date from
1998, available at the TIGER Map Server (http://tiger.census.gov/cgi-bin/mapbrowse-tbl).
The maps on this site are public domain, and you can specify
latitude, longitude, marker positions, and more in the URL. If you
want to put a bunch of markers on the map (such as Wi-Fi hotspots),
see the instructions at http://tiger.census.gov/instructl#MURL.
The Tiger web server is loosely maintained by the Census Bureau and
is not always in a working state.

One of the best resources for free/open source geographic information
is the FreeGIS project (http://www.freegis.org/). This site contains
an overview of the massive world of free Geographic Information
Systems (GIS) software and provides software on CD-ROM. FreeGIS also
acts as a central point for communication and collaboration on free
GIS projects. You can browse the software by category at http://www.freegis.org/browse.enl and its
list of geographic data (including maps and other geographic models)
at http://freegis.org/geo-data.enl.
