The urban limit/boundary is legal (defined by law) here in Brazil. It may englobe areas that still lack a specific use or are not yet populated. It's not only a simple sum of the landuses. It determines, for example, the area that is taxed by the municipality (the urban perimeter/area) or by the federation (the rural area). Example: http://here.com/-22.3837691,-47.3933969,12,0,0,normal.day It's the greyish areas englobing the cities. About mapping it, I see it exactly as mapping administrative boundaries: reuse nodes/ways as needed (or as possible, or as wanted). _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
