TechFest 2009: GeoLife 2.0

The increasing availability of GPS-enabled devices is changing the way people interact with the web and brings a large number of GPS trajectories representing peoples’ location histories. GeoLife 2.0 is a location based social-networking service on Virtual Earth that enables people to build connections with each other using their location histories. By mining the similarity between location histories, this system can help a user automatically discover potential friends in a community with similar interests. This system also enables travel experts who can help plot the ideal sight-seeing locations for you to visit in any part of the world.
