Hi All,
I'm a Geography undergraduate student here in Texas and have access to some pretty neat GIS cartography software. I went wardriving around my neighborhood tonight and got a sampling of access points (SSID, MAC, signal strength, WEP, etc). I wrote a little Perl script to convert KisMac's output into an ArcMap-friendly format and plotted some access points overlaid above a street map of my town. I didn't spend much time on this but the results were pretty neat. I now have a visual representation of every visible AP in my area. Now I would like to take this to the next step: I want to make a rasterized map of WiFi signals that covers my neighborhood in greater detail. I want to walk up and down my street, GPS and iPAQ (or powerbook) in hand and get multiple samples for every access point I find. I want to plot these samples and create visualizations of the wireless signal "fields" in my area.
Here's my problem: all the WiFi-sniffing software that I've used creates only one record of each access point found. I need something that will record SSID, MAC, and (most importantly) signal strength and location for every packet that it sniffs. I realize that this will probably be a lot of data.
It looks like you'd like to get the lat/long for the AP when its signal strength would be the highest rather than just when it gets detected. Right?
Has anybody here experimented with this stuff already?
