Metl Kismet GPS Plotter - Google Earth Edition
I've been contemplating how to better visualise war-driving data, and after Cam demoed the Airmagnet site survey tools while on the 802.1X Roadshow (9 city australasian tour - I was talking about 802.11i), I decided that I should write some signal-strength interpolation code on top of my existing MKGP backend.

So, after a mid-week math-bender, I've got a working rig, and the results are pretty good. There's some limitations in the way the interpolation is bounded, but overall, you get a pretty good idea of how 802.11 coverage looks in urban environments.

I'm still tinkering with the code a little, cause sometimes the interpolation goes off on wild goose chases, and it's a RAM-hungry pig. I need more data to test it with, so I'm contemplating whipping up a web-service so you can upload your Kismet logs and get Google Earth .kmz files out. That way I get to test it more, and people get to play with the output and make suggestions. If you've got some logs you're willing to share, drop me a line.

Oh, and mad props to Google and, uh, the Cold War for this neat tech. The new orthophotos of bits of NZ are great. 		Last Update: 2006-12-18 23:52:41

Three Telecom Wireless Hotspots covering the Newmarket shopping district. Compressed street coverage is typical of ground level deployments in urban areas. Interpolated signal strength coverage for one of REACH's commercial hotspots. The AP appears to be placed to cover Auckland's High St, which you can see that it does quite well. I've implemented filled-polygon rendering with height for signal bands, but while I wanted it to be cool, it actually doesn't really add much. It also helps to highlight the interpolation-grid bounds (see the jaggy edge on the right?), which detracts from the prettyness. Action shot! Wow. Geeking is so exciting huh?
