To improve the map quality in the Republic of the Congo, we propose to make data improvements by sharing challenges, and when appropriate, fixing data errors, and adding or editing certain kinds of geometry.
How to participate
Anyone is welcome to contribute to this project by participating in our MapRoulette challenges. Here is the extended documentation for using MR. Note that sometimes additional instructions are provided within the challenges.
Challenges
Quality check challenges

- [Tag area=yes on object without feature type](https://maproulette.org/browse/challenges/19445)
The area=yes tag is required for some closed ways when used to define a polygon. For closed ways with other tags, there is an assumption that the way defines an area. In some circumstances, a closed way may define both a closed polyline and an area. When tag area=yes is used, it is expected that one of the necessary accompanying tags is also found.
- [Polygon has self-intersection](https://maproulette.org/browse/challenges/19443)
The necessary edits will be made to fix cases where the tag on a way indicates that the object is a polygon feature, but the way does not meet the definition of a closed way because it is self-intersecting, or ways in a relation with the same role form a self-intersecting polygon
Geometry challenges

- [Missing Roads](https://maproulette.org/browse/challenges/21829) (regional challenge for Central Africa)
Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing.
Missing Highway Surface
Click to expand.
- [Add Surface to Highway](hhttps://maproulette.org/browse/challenges/38268)
The goal of this challenge is to identify and add missing surface tags on a road network. We queried OSM for ways with certain highway=* values where the surface tag was missing.
Geographical scope
Data improvements will be made across the whole country.
We will follow the Organised Editing Guidelines for this project. TomTom will not make any edits until two weeks after the project announcement. Here is our Organised Editing page, including a list of our editors.
How to find TomTom's edits
All edits made by our team have the hashtag #tt or #tomtom.
