What would be the best way to triangulate a wireless network passively. Are there tools available? Algorithms? Libraries?
My goal would be to create a relative map of various objects that sends or receive signals using signal strength (DB's), signal/noise ratio, signal phase, etc. from a few location points. With enough sampling, i'm guessing it would be possible to create a good 2d/3d map.
I'm searching for stuff in any language / platform.
Some keywords: wi-fi site survey, visualization, coverage, location, positioning
Thinking about using kismet to gather the data and then process it. Maybe Free Space Path Loss for RF in the 2.4Ghz range to calculate a relative distance. And optionally try to use RF obstacle attenuation estimation values (based on some user input) to give better estimates. Then use trilateration to generate possible relative coordinates.

Wireless triangulation is a method of determining the location of wireless nodes using IEEE 802.11 standards. It is normally implemented by measuring the RSSI signals strength.
Wi-Fi Signals Can Identify You Through Walls and Even Track Your Movements. It's fair to say that Wi-Fi has become a pretty indispensable part of modern-day life, but it seems the technology can do a heck of a lot more than just stream data to and from our digital devices.
Wi-Fi location tracking, also known as Wi-Fi Positioning System (WPS), takes the concept of Global Positioning System further. Instead of relying on satellites, it uses Wi-Fi routers and smart devices (Wi-Fi access points) to pinpoint a phone, tablet, or laptop more accurately than a GPS does.
Wi-Fi positioning system (WPS, also abbreviated as WiPS or WFPS) is a geolocation system that uses the characteristics of nearby Wi-Fi hotspots and other wireless access points to discover where a device is located.
You can't use the GPS technique because the timing is nothing like accurate enough. The best you can do is Trilateration based on the signal strength from each base station and assume that range is proportional to signal.
You will probably need to force a connection to each base station in turn in order to measure the signal strength.
