Bahrain | Data Improvements
Project description
Goal
To improve the map quality in Bahrain , we propose to make data improvements by sharing challenges that can help fix data errors, and add or edit certain kinds of features or tags.
When appropriate, our team will also work on these challenges. If a challenge is more suitable to be solved without organised help, we will leave it for local users interested in completing the tasks. Challenges like this will be indicated as such in the overview below.
How to participate
Anyone is welcome to contribute to this project by participating in our MapRoulette challenges. Here is the extended documentation for using MR. Note that sometimes additional instructions are provided within the challenges. We also strongly encourage you to make use of the resources listed in the OSM wiki section Bahrain Guidelines while you are editing.

Bahrain - Updating Junctions and Improving Highway Network This Challenge aims to improve the quality of road network in OpenStreetMap, mostly related to junctions. You can improve the highway network by remodeling junctions, changing dual and simple carriageways, adding or removing connectors and other highways, aligning highway accuracy, and tagging them accordingly.
Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing.
Edits based on User Feedback
We will make improvements to OSM based on user feedback submitted for the TomTom map after comparing and ensuring that it is also valid for OSM.
Here is a list of the types of edits to be made, provided they do not conflict with others’ edits and a local source is available:
-
Highways
- Adding highways
- Realigning highways
- Adding or adjusting bridges, tunnels, layers, or relations
- Updating lanes
- Updating traffic signs
-
Addresses
- Adding or correcting addresses
- Updating the position of address nodes, usually when an object has multiple addresses
- Adding or correcting names of ways
-
POIs (Points of Interest)
- Adding POIs
- Correcting POI locations
- Adding or correcting POI information
- Resolving POI-land use discrepancies
- Handling POI closures
-
Land Use
- Adding land use
- Modifying existing land use extent
- Adjusting building shape
-
Buildings
- Adding buildings
- Updating building type
- Adjusting building shape
-
Water
- Adding or realigning rivers, streams, and lakes.
Missing Buildings

Missing buildings were detected after a spatial comparison with TomTom's map database. The tasks in this challenge focus on physical structures such as residential, commercial, and industrial buildings.

TomTom organised editing
We will follow the Organised Editing Guidelines for this project. TomTom will not make any edits until two weeks after the project announcement. Here is our Organised Editing page, including a list of our editors.
How to find TomTom's edits
All edits made by our team have the hashtag #tt or #tomtom.
Sources for editing
- Esri World Imagery
- Bing Maps Aerial
For some OSM map edits TomTom editors 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 themselves. The proprietary sources will be ground-level imagery and GPS traces, both collected by TomTom's mobile mapping vans. On occasion, we will also use sources collected from a field survey by one of TomTom's sourcing specialists who have visited the location and collected data to support the required map updates.
How to reach out
If you have remarks about a specific edit of ours, please drop a comment in the changeset, and we will do our best to respond thoughtfully. Or, you can also:
- send a message to the project lead Hajar El Ouafi,
- join the conversation in Telegram Openstreetmap Asia,and Talk Asia Mailing list
- email [email protected] for general questions about TomTom's activities.
The 'Sources for editing' section updated with the below information-
- Removed Maxar Premium Imagery from the list as it's not available anymore in OSM
- Added a description of proprietary sources to support editing
