Routes marked by OS as "Other Route with Public Access" will most probably be routes that appear on the local Highway Authority's "List of Streets Maintainable at the Public Expense", but are not maintained to a standard for regular motor traffic. They will generally be Unclassified Highways (i.e. not an A, B or C road) and unless there is a specific Traffic Regulation Order to the contrary, there will be full vehicle, horse and pedestrian rights over them. As far as tagging is concerned, I would strongly advise against designation="other routes with public access", designation=orpa and similar. The "Other Route with Public Access" is an OS-specific term, and even if that status hasn't been copied from OS, such tagging may give the impression that it may have been -- which is not something we want to give or accidentally encourage. Instead, I would suggest that mappers do their best to determine the precise status of the route in question -- which is most likely to be an Unclassified Highway. Then an appropriate designation=* tag can be given (e.g. designation=unclassified_highway). Despite a route technically being an Unclassified Highway, if the route isn't suitable for general motor traffic, I would avoid tagging it with highway=unclassified -- as that would be misleading to data consumers. Instead I'd give it a suitable highway tag based on the physical condition of the route -- probably highway=track or highway=service. Appropriate access tags should also be used (access=yes if everything is allowed, and foot=*, horse=*, bicycle=*, motor_vehicle=* etc if not) since routers and other tools shouldn't be expected to translate UK-specific terms into access defaults. There are some more details about different types of Rights of Way and the implied access rights at http://wiki.openstreetmap.org/wiki/User:Rjw62/PRoW_Table To determine the precise classification of a road/track, you'll need the "List of Streets Maintainable at the Public Expense" from the local Highway Authority (usually the County Council or Unitary Authority). Some councils will have online maps of their Highways, but these will generally be derived from OS data, and so we're unable to make use of them. For details about getting hold of this "List of Streets" and permission to re-use it in OSM, see http://robert.mathmos.net/osm/prow/council-docs.html . There's a (short) list of councils known to have given permission so far at http://wiki.openstreetmap.org/wiki/Contributors#Information_in_the_.22List_of_Streets.22_maintained_by_local_councils Hope that helps, Robert. -- Robert Whittaker _______________________________________________ Talk-GB mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-gb
