if you can work out all the info you can on the ap it may help (Like looking at the MAC for Vender and Model to find the DB out put), all of the maping software i have seen todate for netstumbler use's 2d maps ( if your trying to DX an AP you need to take all that you can find ) it whould be a good idea to move to a 3d gps - maping system ( off the top of my head you could use the SRTM ( info on SRTM [
http://www2.jpl.nasa.gov/srtm/ ] ) info on nasa's web page and other way's to get info (
Http://www.cplus.org/rmw/dataen.html ) there is one program that dose RF radio progation modeling that dose a good job i use it all the time in my army job working with sincgars radios (

could you try and use the time of request to becin to get a rufe idea of range, might be a way to but out the reflecions
i.e. (becin time - repuest time) * 299,702,547 = m to AP i know you have the speed of light changing (
http://www.what-is-the-speed-of-ligh...ive-index.html )as the H2O in the air, and the time it take the ap to think will throw off the #'s but might work for a rule to cut down bad data.
i have had the same thoughts on needing to work out where APs are before, and love to see someone that can take it on good luck.

1. this is one map of what Radio Moble dose
2. this is one of the things that i have found that might be a good idea to tie in to the maping system
