OpenStreetMap is community of people creating fully open map database. From roads, shops and rivers to tourism attractions, hiking routes and hospitals, with all kind of detail. Anyone can contribute (and as someone quite involved in OSM: if you want to map something, especially area near you: you are welcome!). Overture is a new group of companies releasing some datasets on open licenses, but methods used to create them remain proprietary. Some of released data is theirs, many datasets are repackaged OpenStreetMap data.
