Mmh, type=tunnel is already in use [1] but it is used for the whole tunnel, e.g. to combine several tubes and the infrastucture like escape ways and air-system. We could use a tag like tubes= or number_of_tubes= for the relation and draw the outline. fly -- [1] http://wiki.openstreetmap.org/wiki/Relations/Proposed/Bridges_and_Tunnels _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
