War Driving

You can use NetStumber with your GPS to get a geo-plot of Access Points in your area. I used NetStumber to collect the GPS location data, then imported it into a neat little program by Doug Cox call USAPhotoMaps. It downloads topo maps from Microsoft's TerraServer Web (unfortunately some very old data here). Doug's website is http://jdmcox.com. Below is a plot of my wardriving trip around my neighborhood. As you can see, the topo map was taken before the houses were built. However, some of the other sections are pretty up to date. Green dots indicate "open" (unencrypted) APs while red dots indicate that encryption is enabled (I have many carelss neighbors!!)

Enjoy!
