This is pretty slick: Nora Event Locations Its Google maps embedded into the Nora website. Nifty! Its XML driven so when they change locations (which is pretty often), its a quick and easy fix up on the xml file.
Also nifty, is plotting NetStumbler data (the green markers are open WAPs and red are encrypted ones). Again, its all XML AJAX driven. I wrote a quick little PHP script to convert NetStumbler’s summary text file into XML. What is a LOT of fun is browsing the map and switching it over to hybrid view. And if you’re wondering, map roughly plots my path to work. If you know me well enough, you can probably pick out which router is my router and then identify where I live. Shh! Don’t tell anyone though.
