There’s a neat bit of software that you can use in conjunction with your GPS unit and Google Earth to show your position in realtime while Stumblin’.
Using gps2geX, the software generates an “on the fly” KML file which is loaded in Google Earth. The co-ordinates for gps2geX are updated from the gpsdX daemon, which is also being used by KisMac, so no one app is taking sole control of the GPS unit.
The results are pretty cool. You can see your exact position on Google Earth, updated as per your settings in gps2geX, Google Earth even tilts and pans the camera around based on what direction and speed you’re moving in.
So if you’re driving around looking for wireless networks, how are you streaming images in Google Earth? Ahh, good question. I use my Sony Ericcson K800i as a bluetooth modem. I’m on T-Mobile’s Web’n’Walk Plus service plan, an unlimited (yeah, with the usual cavaets) internet access plan. A drive around my home town worked well, probably because I had a lot of imagery cached already, but it all seemed to work just fine.
