The candidate for edits such as missed or wrongly mapped on OSM speed limits, turn restrictions, turn lanes, oneways, which is identified automatically by the internal tools built by Mapbox developers based on GPS traces.

Types of Activity

Here is list of features we commonly focus on:

• OSM speed limits
• Turn restrictions
• Turn lanes
• Oneways
• Road geometry

Geographical scope

Data improvements will be made worldwide.

Tools

Team will use OSM ID.

Sources

• OSM imagery
• street-level sources such as Mapilary or Bing Streetside
• Tiger Roads
• KartaView
• Mapbox Imagery
• Source with ODbL license

For some OSM map edits Mapbox will use proprietary sources for support. These will typically be in situations where there is not sufficient evidence using the available sources in OSM editors. The proprietary sources will be ground-level imagery and GPS traces, collected by our drivers during testing.

Timeframe

This project is ongoing and will be continuously active without any time constraints.

Results

The results of our review made by our team in OpenStreetMap will be displayed quarterly in the /mapping repository.

Contact

We welcome feedback from local mappers as local knowledge always prevails. If you have any questions about a specific edit done by the Mapbox team or want to suggest some improvements in the editing process you can contact osm-edit-escalations@mapbox.com or post a comment in a changeset.
