MapRoulette is a micro-task platform for OpenStreetMap. MapRoulette.org gives you small Tasks you can complete in under a minute to improve OpenStreetMap. Anyone can create groups of tasks, called Challenges, that the community can complete together.
Besides the website maproulette.org, there is also a full API that you can use to integrate MapRoulette with your own tools.
On this wiki, you will find all the resources you need to use MapRoulette.org, create and manage Challenges, see statistics and interact with the MapRoulette API.
