I was toying around with that a while ago, and must admit its fun to do
A thread with some more info ;
the version of google earth that you are using has some effect on the way the APs are shown in the map, so you might want to try what it looks like on different versions of google earth.
KNSGEM was what I liked best if I remember correctly, it just can get very very cluttered if you live in a city like I do, its scary to see how many APs there are out there !
Quite amusing to see that some essids with names like "hacked by xxx", I saw a couple of those.
I basically did the following (based on BT3F);
Insert usb GPS
Should then see the USB0 in the listing.Code:ls -altr /dev/tts/
Then start gpsd
And then start kismet and give it a few minutes to start the GPS data flowing.Code:gpsd /dev/tts/USB0
(in my case it took between 2 - 5 minutes...)
Then I used KNSGEM to get the kml files for viewing with Google Earth.
