WiFiMaps.com releases massively large, detailed wardriving maps of Seattle: In conjunction with a University of Washington course. I can't describe it better than Drew:
Dr. Philip Howard from the communications department has been teaching his students about technology, ideas, people, and how culture is affected by these new concepts. Their project allows them to gain some practical experience while exploring Wi-Fi as it pertains to them and the people around them. Involving 100 students, this project is one of the largest collective efforts to map Seattle's wireless landscape.
WiFiMaps.com is a website which provides interactive maps of Wi-Fi installations, as seen by wardrivers. This collaboration served to create critical mass for the website to provide printable maps, in addition to on-screen maps that exist. Also, this paves the way for other universities and groups interested in orgznizing detailed scans of their city to have a way to actually accomplish this, and have visual results.
The files are BitTorrented because of their enormous size (over 100 and 300 MB). [link via Slashdot]
