Micro-task platform for OpenStreetMap
MapRoulette (MapRoulette.org) is a microtask platform and web application for OpenStreetMap. Grab yourself a small task and start improving OpenStreetMap!
User and Developer Documentation
- Here is the documentation and other learning resources.
- The code and issues are available on GitHub.
- There is also a blog.
The MapRoulette API lets you create and manage Projects and Challenges. See the API documentation.
Challenges and Projects
Tasks are divided into Challenges. Anyone can create a Challenge using the built-in Wizard. You can use an Overpass API query as the source of your tasks, or a GeoJSON file you already have.
A Project groups one or more Challenges. A Challenge can be part of more than one Project. Each Project has its own management page where you can see Leaderboards and progress.
If you see bad edits in OSM that you think are to be blamed on a poorly designed MapRoulette Challenge, please see here for instructions on how to report the Challenge.
As a result of the License Change, a lot of OSM data was deleted or reverted back to a previous version. The first version of MapRoulette was geared towards repairing this damage by identifying all the ways that were gone and inviting users to re-add the removed ways using the standard OSM editing tools.
The remap-a-tron proved to be a very successful tool. Perhaps it could be repurposed to help get other types of map bugs fixed? At State of the Map US 2012 in Portland, the next iteration of what would become MapRoulette was announced: the Un-Zorro-Tron, to help fix Zorro Ways in the United States OSM data.
