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

Lynn (D) - KJ4ERJ - Author of APRS-IS for CE (Windows Mobile actually) - 
Tracking as KJ4ERJ-12
