[OSM-talk] [HOT] A tool for picking up settlements tagged as a single building?

[Jo]

Hi John,

When I first saw your message, I looked into Overpass API, but no luck. In
JOSM areasize would definitely work. You'll have to find a sweetspot around
100-

so

building areasize:100-

or possibly 500 or 1000.
