MapTiler provides robust and regularly updated maps, drawing largely from OpenStreetMap (OSM) data. As a MapTiler user, you might sometimes notice inaccuracies or outdated information in your maps. The best way to rectify these issues is by directly editing the data in OSM. For more information on the origin of MapTiler Planet data and updates, please refer to the origin of the MapTiler Planet data and the MapTiler Planet updates documentation. This article will guide you on how to contribute to OSM, ensuring that your corrections will be reflected in future MapTiler updates.

Why Edit OpenStreetMap?

OpenStreetMap is a collaborative project where anyone can contribute to improving map data. When you edit OSM, you not only enhance the quality of your MapTiler maps but also help maintain a high standard of mapping for users worldwide. OSM occasionally suffers from data inaccuracies and vandalism, especially in disputed areas, so community contributions are crucial.
