We source our cartography via Openstreetmap. If you are sure that data is incorrect, you can edit the relevant area in openstreetmap yourself. Have a look at this handy guide, which will walk you through your first Openstreetmap edit. If you happen to already know how to edit Openstreetmap, well, then edit away! If you’re absolutely confident that the error in our maps is unrelated to Openstreetmaps, drop us an e-mail at help@printmaps.net and we will look into it.
