Interesting timing! I've spent the day working with GD and
OpenStreetMaps.org to visualize and plot various APRS-IS collected
data! If you've not heard of OpenStreetMaps.org, check them out. A
free map source with tiles of various zoom levels that are stitchable to
make any arbitrary map with details. Of particular programmer interest
is http://wiki.openstreetmap.org/index.php/Slippy_map_tilenames
