OpenStreetMap is a crowdsourced map of the world created by volunteers. It has grown exponentially from just Steve Coast in 2004 to over 1 million mappers in 2010. Anyone can contribute by collecting and editing map data using GPS, mobile devices, or online tools. Contributors benefit from an open, up-to-date map of their local area while helping create a rich map resource for all. New mapping tools like Mapzen launching in November aim to make the editing process more intuitive and connect mappers through social media.
