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
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).
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).
