Hong Kong | Data Improvements
Project description
Goal
Improving the map quality in Hong Kong by sharing tasks that can help fix data errors and/or add certain kinds of features.
Challenges
Quality Check Challenges
Click to expand.
-Fix Building and Highway Intersections Identify and fix, if needed, cases where a way with tag highway=* intersects with a building.
-Fix Intersecting Buildings Identify and fix, if needed, situations where a building intersects with another building at the same layer.
Active Challenges
Add Highways
- Hong Kong - Add Highways Identify and add if needed, one or more missing ways. We spatially compared TomTom's in-house road centerlines with the OSM road network and identified missing way locations.
Quality Fixes
- Hong Kong - Fix Intersecting Buildings The challenge aims to identify and resolve cases where buildings intersect at the same layer in OSM, enhancing map clarity and visual consistency. Tasks are generated through spatial comparisons of building polygons.
Edits based on Map 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.

-

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. We will also add the #tt_mapfeedback to the changeset if it is an incidental edit resulting from user feedback.
Sources for editing
- Mapbox Satellite
- 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 Kiran,
- join the conversation in the OpenStreetMap - Hong Kong Server channels,
- email [email protected].
