That's the point. Is it "legal" or just the sum of all urbanized
"landuse" 's (residential, industrial, retail). Does it include
backyards, garden, orchard, etc ? The limit is often clear on the road
(first/last building + road sign) but fuzzy on aerial imagery if you
want to draw the area. And if all landuses are already mapped, do you
add a new polygon reusing existing nodes or do you create a
multipolygon relation (splitting the existing landuse) or you just
collect the sum of existing landuses ?
