Alter

Know something we don’t?

OpenStreetMap has no tag for how loud a room is, and almost nobody maps power sockets. If you have been to Alter, that is exactly the gap you can fill. A person reads every report.

Reports are checked before they appear, and they are shown separately from the OpenStreetMap data — we never merge them into it. We store no name, no email and no IP address; see privacy. If you would rather fix the map itself, edit the venue on OpenStreetMap and it will reach this page on the next import.
