June 2021: As part of on-going work to improve the quality of OpenStreetMap data, we recently used osmlint-osmium and osmlintfor detecting issues related to road network data in France. In total, there were 45808 issues detected across 11 types of linters.

August-September 2021: Now we will use internal mapbox data validation jobs that search OSM data for errors.

Here’s a link to our Github mapping ticket


We plan to start reviewing detected issues by the end of next week, and editing OpenStreetMap data to fix valid issues.

In August-September 2021 our team is going to start a permanent mapping project in France. Once a week there'll be an upload of data and the team will close these issues.


We will use existing OpenStreetMap editing tools, and using the #hashtag #mbx_france_roads
