Have you discovered an error in one of our maps that you want to tell us about? Have you noticed a change in the landscape that we have not yet included in our products? Simply use the “report a problem” function in our map viewer at map.swisstopo.admin.ch to notify us of any changes, errors or additions. You can illustrate your description with a drawing which you can create directly on the map and send to us with your message. You can also send a file such as an image of the change situation.

map.swisstopo.admin.ch also works in your smartphone’s web browser, allowing you to send us a message while you’re out and about. 

Your messages and suggestions help us to continuously improve our maps and geodata and we would like to thank you in advance for your valuable suggestions and information.
