OpenStreetMap is a free editable map of the world created by volunteers. It began in 2004 as an alternative to proprietary map data. The summary provides high-level information about OpenStreetMap's origins, growth, and importance. Over 260,000 registered users have mapped over 18 million points of interest and 11 million miles of roads across 69 countries. Analysis has found OpenStreetMap data to be of high enough quality to be used for many purposes. It is created through crowdsourcing rather than centralized production, representing a paradigm shift for data creation.
