Hello and Welcome to MapRoulette.

MapRoulette is a micro-task web tool for OpenStreetMap. It 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.

This is the third major version of MapRoulette. The website has been completely redesigned and contains a lot of new features compared to the last major release.

On this wiki, you will eventually find all the resources you need to use MapRoulette, create and manage Challenges, see statistics, interact with the MapRoulette API, and contribute to the MapRoulette source code. Have a look at the content menu on the right to see what documentation already exists.

The MapRoulette team appreciates your bug reports, suggestions for new features, code submissions and any other ideas and offers of help very much. Thank you in advance! Please create an issue, or you can email us at maproulette@maproulette.org.
