 Cyclists use good apps to navigate themselves through a city. However, good cycling apps need good data, but where to find good and reliable data? The answer is OpenStreetMap, OpenStreetMap or OSM is an online map where volunteers contribute using their local knowledge. This means that it's a very reliable source of open data, especially for bike dated Brussels. We want to ensure that OSM data in Brussels is correct for cycling data. To meet this goal, we have created an online tool that will be used by the local mapping community. Our tool uses data from the Brussels government, which is used as a reference. Our tool then automatically compares the Brussels data with OSM. The result of our work is already evident. In less than one week, most of the issues on OSM for Brussels is resolved. This demonstrates the potential of OSM to provide the best bike data all through a community supported by a simple validation tool.
