An early influential Google Maps mashup now gives users the chance to change mapping imagery. The GMaps Pedometer (our GMaps Pedometer mashup profile) has six different tile options, the most recent of which is OpenStreetMap, the free editable map of the world.
Google continues to expand its third version of the maps API to include features already in the second version. Most recently, they've added driving directions, which gives programmatic access to the routing data between two points. As with the rest of Maps V3, which was released in May, the team took a fresh approach, so some interfaces have changed.
