We receive our data from several sources, one of it is OpenStreetMap. That's a great project that enables volunteers worldwide to gather data on streets, railway tracks, rivers, forests, houses and much more.
The best about it: everyone can be a part of it. If you wan to add something to the map yourself or have found an error you would like to correct, all you need to do is go to the project's website, and follow the step-by-step guide. With the next map-update, the data will become available in the komoot-map.
Hint: Use the key combination CTRL (Apple: CMD) + ALT + click on the map with your left mouse button. This will open the OpenStreetMap view in a new tab. From here, you can directly access the editing mode and make changes. They will be displayed in our app by the next day normally. In our route planning, the changes will be adopted about max 3 weeks later at the moment.
