Review the project description in the /mapping repository and the linked OpenStreetMap documentation, especially the listed road-attribute references and team wiki. Before starting, identify a specific documentation change or deliverable; done is not defined by this issue beyond the ongoing editing project and quarterly results.

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.
