How to help improve OSM maps

OpenStreetMap (OSM) provides map data for thousands of web sites, mobile apps and hardware devices, including It is built by a community of people who contribute and maintain data about roads, trails, cafés, railway stations and much more, all over the world. Anyone can contribute and it is easy to do so.

You can make changes to existing features on the map such as whether cycling is allowed on a road, or you can add new features, for example a new footpath that isn't currently shown. Any changes you make to OSM will normally appear visually on the OSM maps used by maps within 7 days. It will take longer for changes to flow through to our routing engine, which is used to calculate routes and provide terrain data, as this is updated once a month.

The Surface and Allowed Access map attributes are two of the most important ones used by, as these impact route calculations, so the following instructions explain how to update these, but there are various other attributes you can change.
