Hi Simon, Nice feature!

OK, I see potential for this, with two prerequisites. The first is easy to get right - simply make sure enough rights are granted by the contributors to allow inclusion in OSM (not of the trail, but of what might be derived from it). The second needs some thought, but is probably still pretty doable - basically it would be an annotation option. As you say, the trace lacks enough context to actually map anything from it. But suppose a contributor were to provide a free text annotation, which could look like this?: From Crone car park to the waypoint 123 is a wide gravel track suitable for vehicles but only for use by forestry service. Ignore the 50m detour half way up this section. At waypoint 123 there is a stile and after that I stuck to the beaten track [description of track characteristics]. After coming off the summit I was going through open country, so do nothing with that. The idea being that any contributors who provide a usable description of an identifiable section of their track will help us to improve the map. Something that will really help with this is that by the end of 2012, Bing will have complete aerial coverage of Ireland, sufficient by and large to see many mountain tracks, but not necessarily to determine their characteristics. So the aerial imagery will help get around the fact that the GPX traces are imperfect. So there it is, half-baked, but I think there's a basis there for something useful. Take care, Dermot -- -------------------------------------- Igaühel on siin oma laul ja ma oma ei leiagi üles _______________________________________________ Talk-ie mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-ie
