no, if this would be possible there would be no sense at all to map areas. You can't see sidewalks as "just another lane", because they tend to be quite irregular in certain settings (unlike lanes which usually keep their width and have no corners and other weird points). The point of mapping areas is to be able to map irregular street areas, changes in the sidewalk and similar. That's why I proposed the area relation: to be able to map these details, to be able to add topology details like kerbs and lower kerbs and similar issues. cheers, Martin _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
