199 The OpenStreetMap project is a collaborative effort to provide free maps that anyone can use or edit. Over the last two years the project has grown from a one-man effort, to become an international Foundation dedicated to the provision of Free Geo-Data.. An active community of over 2,500 members regularly contribute GPS tracks, edits and code, to what is fast becoming one of the most dynamic publicly accessible geo-databases in the world. In May 2006, a group of OSM members met on the Isle Of Wight, with the aim of mapping as many of the Island's roads and footpaths as possible in one weekend. The meeting was a huge success; an estimated 90% of the Island's roads and footpaths have now been mapped, making OSM's database the most up to date publicly available map of the County. The first two years of OSM have undoubtedly proved the concept of open collaborative mapping. The organisation must now mature into a Foundation that has firm ethical and legal codes as well as an infrastructure that can support the activities of a rapidly expanding and diverse international membership. This paper looks at the last 2 years of OSM and explores some of the anticipated challenges that the organisation faces over the next 12 months.
