Map Maker for Developers. Tiles from Google’s Map Maker crowdsourcing effort are now available in the JS and static maps APIs on an opt-in basis. Maybe I’m misunderstanding something here, but Google Map Maker seems like a big step backwards for open geographic data. People donate their mapping efforts to Google, who keep them—unlike OpenStreetMap, where the donated efforts are made available under a Creative Commons license.
