MapRoulette 3.1.1 Release Notes

Posted by mvexel on 19 November 2018 in English.

MapRoulette 3.1.1 is now available on Here’s what’s new!

Mapillary layer

Mapillary images are now available as an overlay on the map. If you’re zoomed in far enough you can select the Mapillary overlay from the Layer dialog.

This is a work in progress. Let us know if you have any suggestions to make it better! And yes, we plan to support OpenStreetCam images soon as well.

Rebuilding Tasks

MapRoulette now supports rebuilding tasks from Overpass based challenges as well as local and remote GeoJSON challenges. You can use the ‘Rebuild’ link at the top of you Challenge maintenance screen to start the process. For Overpass based Challenges, it will simply re-run the Overpass query. For remote GeoJSON files hosted someplace else, it will reload the GeoJSON from there. For local GeoJSON challenges, you will be prompted to select a new GeoJSON file to upload from your computer.

For a rebuild to work, you need to have assigned unique identifiers to Tasks in your Challenge. MapRoulette uses these identifiers to match the new Tasks with existing ones. We created a wiki page to explain this in more detail.

Public Leaderboards

Each Challenge now has a public Leaderboard page! You can access it on the Challenge Browse page.

The Challenge leaderboards work the same as the overall Leaderboard. You can select one month, three months, six months or a year for the period. You get 5 points for fixing a Task, 3 for marking it as Not an Issue or Already Fixed, and 1 point for marking a Task as Too Hard.
