Servus Matze! I was assuming the answer would be "no", since previous reuse of PSI licences have had troublesome clauses in them. This one, though, seems good, so yeah, I see no obstacle. Except perhaps one... And this would make it completely out of the question: you can't tell where they got the trail geometry. If they walked it themselves, well and good. But it's probably more likely they did one of the following: * Traced it from unknown imagery, likely Google Earth * Traced it from Ordnance Survey Maps * Derived it from some official GIS sytem they have which itself is fed from OS data That being so, I would, before using any data, outline your interest, indicate your desire to use the data under the PSI licence, but asking for assurances that the tracks were not derived from a source preventing them from offering them so openly. This is, of course, a much more cumbersome thing for you to do, but you'll agree that the consequences of using the stuff in the wrong would be much worse...
