Description

### Background

As part of on-going work to improve the quality of OpenStreetMap data, we recently used [osmlint-osmium](https://github.com/osmlab/osmlint-osmium) and [osmlint](https://github.com/osmlab/osmlint) for detecting issues related to road network data in France. In total, there were 45808 issues detected across 11 types of linters.
Our plan is to review detected issues in Paris and areas in Northern France, and fix any valid issues in OpenStreetMap. [Link](https://wiki.openstreetmap.org/wiki/Organised_Editing/Activities/resolve_linting_issues_in_France) to the OSM Wiki page.

### Timeframe

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

### Tools

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

**Editor**: iD or JOSM
**Satellite Imagery**: Bing, Maxar, Esri
**Street Level Imagery**: Mapillary, Other open sources if available

### Contact Person

We welcome feedback, suggestions, and insights from local mappers. If you have questions about this work, or a specific edit by our team, please reach out to Natallia (natallia.zhouner@mapbox.com) or post a comment in a changeset.

### Examples

Impossible angle or what we usually call “dragged node”. Link to example you can find [here](https://www.openstreetmap.org/edit#map=20/46.25641/-0.54262)

There are problems with the connection of roads near polygons, especially parking lots. Parking lots in France are often mapped by polygons without lines (roads) inside the polygon and since there are no lines inside the polygon, routing will not work. Such example you can find [here](https://www.openstreetmap.org/edit#map=20/48.21981/-1.70019)

Also found unconnected roads. To be routable, they should be connected into the road network. You can find example [here](https://www.openstreetmap.org/edit#map=20/48.05248/-1.39666)

One more example where road is connected to gate not to the road [here](https://www.openstreetmap.org/edit#map=20/47.49060/-0.55362)

Research direction

Start by reading the linked OSM Wiki activity page and the linter output files, then review the listed examples in iD or JOSM. The work covers 45,808 detected issues across France, with no single code entry point or bounded task named. Done means valid OpenStreetMap data issues have been reviewed and fixed using the stated editing tools.
