I think this depends on whether you adopt the "sidewalk as a separate way" method or the sidewalk=left/right/both/no method. In my area of suburbia, I'm using separate ways, so I would likewise use two separate areas. For other areas that use sidewalk=*, such as cities with "integrated" sidewalks and streets (such as Washington D.C.), it might make more sense to use a single area, depending on the local community. That being said, I don't intend to use this tagging yet. I'd be more interested in seeing an integrated method that would allow tagging not only the area of the road, but also separate lanes that allow for turning restrictions, to be used for simulation purposes as well as precise navigation. -Josh _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
