OpenStreetMap is a free editable map of the whole world which anyone can help to build.
OpenStreetMap, which was started by Steve Coast in 2004, allows anyone to create and edit geographical data in a collaborative wiki-like manner and use it for any purpose.
The project was started because most maps that you might think of as free actually have legal or technical restrictions on their use, holding back those that wish to use them in creative, productive or unexpected ways. All OpenStreetMap software is GPL, and content is published under the Creative Commons (CC-BY-SA).
The project has four major components:
- A database containing map data in vector format. Data is annotated using free-form tagging that is managed by community consensus.
- A variety of software tools for editing map data.
- A range of methods for rendering and viewing the data in map form, including on-line slippy maps, SVG, PDF and various hand-held formats.
- A map-data API and static data dump of the whole planet.
Resources for creating the data include:
- GPS tracklogs
- Aerial imagery
- Historic out-of-copyright maps
- Public domain data-sets
OpenStreetMap uses a variety of community and social collaboration techniques to achieve its goals. These include methods such as forums, mailing lists, blogs, RSS feeds, IRC, podcasts, wiki-like collaboration, tagging and, in the real-world, the highly innovative and successful mapping parties.
The project has active communities in more than 40 countries with currently 6,000 registered users. Over 500 individual contributors add map data every month and this number is doubling every 4 months. Many cities in the UK and Europe have already been completely mapped and it's one of our goals to map the whole of the UK by mid-2008.
OpenStreetMap can help change society directly by producing relevant and useful maps that contain features that matter to local communities. But more importantly, the availability of maps and cartographic data is a key enabler for many other projects that seek social change. Amongst the NetSquared nominations, WiserEarth, parkscan.org and Map The Van are just three examples of projects that could benefit from the free availability of our tools and data.
