Google has been recording location data of WiFi APs (no surpise there), too bad the data isn't exported in a friendly way. From what I can tell, anywhere that has been Street View'ed has also had all WiFi AP's recorded as the car passed by taking pictures. This was rather obvious when using the iPhone 2G (no GPS). It would contact some server via HTTPS and (presumibily) send nearby WiFi AP data in an attempt to get a more precise location. Worked great when driving down a street that had been Street View'ed. Whenever an AP from someone's house got in range, it would narrow down the location rather well. As soon as you went to a street with no street view pictures, it would revert back to the less accurate cell tower location. -- Dave _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
