I like Nelson's idea of using a new value for "boundary" to represent this, mainly because the perimeter is not "ground truth" but an invisible "legal definition" that roughly matches the urbanized area. I was wondering if this concept exists elsewhere so that we can even propose such value in a way that's reusable worldwide.
Here Maps represents the urban perimeter in Brazil just like this dotted line across a river near Berlin and the area inside it: http://here.com/52.5804776,13.2183974,18,0,0,normal.day But in the case of Berlin, it could be Here Maps' arbitrary choice, not a legally significant area.
