Mapbox OpenStreetMap

OpenStreetMap is the free and editable map of the world, created and maintained by a huge international community. Mapbox Streets, our customizable map layer of streets, buildings, and places from all around the world, is powered by open data from OpenStreetMap. Anybody can create an account and start editing on within minutes.

Our data team updates OpenStreetMap based on quality analysis and customer feedback. Our principle is to work in the open, these mapping guides are primarily consolidated and maintained by our data team for various mapping projects and on-boarding new team members.

You are welcome to join one of our open mapping projects over on the issue queue and use these best practice mapping guides. These guides are licensed under Public Domain (CC0), if you would like to contribute or have an feedback on these, please feel free to raise an issue in this repository.

Mapbox navigation mapping projects

Navigation mapping forms a large part of Mapbox’s mapping sprints in recent times. Given below are a few examples of some of the latest navigation mapping efforts across US, Canada, and Europe. To get an idea about all our historical mapping projects related to navigation in OSM, look into the mapping repository. Our mapping projects are conducted in the open with active participation, feedback, and validation from the community.


Location Description Start End(ETA) Validation
Mapping turn lanes in 30 US cities Mapping all the turn lanes from satellite imagery in 30 US cities from secondary and above 04/05/2016 Continuing Continuing
Updating turn restrictions in Germany Updating missing turn restriction coverage in 3 german cities: Berlin, Stuttgart, Wolfsburg 29/08/2016 Continuing Continuing
Mapping turn restrictions in Canada Mapping turn restrictions from mapillary in top 5 cities in Canada 22/07/2016 05/08/2016 Completed
Exit and destination mapping in Canada Map the exit and destination numbers in top 5 Canada cities using mapillary 11/08/2016 17/08/2016 Completed

Navigation data tools

  • Mapillary Explorer: Explore navigation related traffic signs automatically detected from crowdsourced street level imagery.
  • OpenStreetMap navigation map: This map is used to add turn restrictions in OSM. It has a detected signage mapillary layer for easy detection of turn restrictions, oneways and a dataset which displays all the valid, invalid and redundant turn restrictions added. Get more instructions on how to use the OSM navigation map.
  • CheckAutopista2: It is a tool to investigate and add highway signboard features on motorways and freeways. For more details look into the github repository for checkautopista.
  • Overpass: The place to query and extract all OSM data related to a specific feature. It has a simple query builder feature that helps in querying each and every feature in OSM. Details about overpass can be found here and here.
  • Knife tool: The knife tool can be used for quick splitting of ways while adding navigation features such as turn lanes. For more details, look here
  • Turn lanes tagging plugin: With this plugin, you can add complex tag combinations for turn lanes at road junctions with ease, and minimize errors. For more details, look here

Country specific navigation guide

  • Images of traffic signs and road markings : Traffic signs and road markings may undergo small changes and specific cases when mapping turn restrictions using Mapillary. There are subtle differences in turn restrictions between Canada, US, and Germany. (This section is to be kept updated with new signages every time mapping is done in a separate country with new conventions)
  1. Turn restriction images in US

  2. Turn restrictions images in Germany

  3. Turn restrictions in Canada

  4. Turn restrictions in France

For more details on cases for turn restrictions and signages in different countries take a look at QA for mapping turn restrictions
