OpenStreetMap

You have set the source for https://www.openstreetmap.org/relation/416471 to http://af3v.org/CarteAF3V/-Carte-des-grands-itineraires-.html , but when I look at that page, it says that the map is copyright and reproduction is forbidden.

Any source used for OSM must either be in the public domain, which cannot be the case here, or must be released, under a licence that has been approved by OSM.

Could you either point me to the grant of an approved licence for the use of data from that web site, or remove any data that you added to the map based on that web site.
