OpenStreetMap US

We are excited to announce that MapRoulette is now part of the growing network of Charter Projects supported by OpenStreetMap US. MapRoulette is an open, collaborative and cooperative microtasking platform for improving map data that empowers users to contribute impactful edits to the map.

An open source project, MapRoulette has become a critical tool for microtasking in OpenStreetMap, used and known throughout the ecosystem. For example, MapRoulette plays a vital role in improving map data for rail transportation safety in the United States, as recently recognized by the US National Transportation Safety Board. In the US and around the globe, MapRoulette serves the mapping community as a user-friendly tool for systematic improvement of completeness, quality and accuracy of map data. Mappers from over 70 countries review more than 40,000 tasks a month. More than 330,000 changesets in 2022 alone can be directly attributed to MapRoulette.

From the MapRoulette advisory board: 

“Gaining Charter Project status will solidify and formalize MapRoulette’s position as a critical piece of OpenStreetMap QA infrastructure. Corporate users already see MapRoulette as a critical tool in their QA and want to support it, but it has proven challenging to harness this energy and align the requirements of corporate users with those of the volunteer OSM community. By becoming a Charter project, we hope to be able to better serve the entire OSM community.”

OpenStreetMap US looks forward to supporting MapRoulette in building a sustainable foundation for the project that includes both corporate and volunteer community members. MapRoulette joins other fantastic projects in our Charter Project program: OpenHistoricalMap and OSMCha. With this addition of MapRoulette, we are excited to see what possibilities lay ahead by creating opportunities for collaboration between these projects and their contributors.
