Mapbox OpenStreetMap

OpenStreetMapは自由で編集可能な世界地図であり、世界各国から参加しているボランティアの手によって作成され、メンテナンスが行われています。私達のMapbox Streetは、OpenStreetMapが提供する全世界の道路や建物、地名などのオープンデータを利用して作成されている、カスタマイズ可能な地図レイヤです。アカウントの作成と編集は OpenStreetMap.orgから、数分程度で開始することができます。

私達のデータチームは、品質分析や皆様からのフィードバックをもとに、OpenStreetMapを更新しています。私達の活動はオープンに公開して行っています。参加はどなたでも可能です。マッピングプロジェクトへの参加は、オープン状態になっているIssueからお願いします。また、マッピングのベストプラクティスガイドも公開中です。These guides are maintained by Satoshi (nyampire) from OpenSteetMap Foundation Japan.

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.

Examples

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

  • 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
