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:
But in the case of Berlin, it could be Here Maps' arbitrary choice,
not a legally significant area.
