It's the Senate wing of the US Capitol Building. It's the eastern third of Saint Peter's Basilica. It's gates 54, 55, and 56 of Tokyo Narita Airport. Moving down to lesser-known structures, it's a dozen houses on the outskirts of Paris. It's a par-3 hole on a Scottish golf course. It's half of an Ikea store in the suburban United States. 10,000 square meters strikes me as a good rule of thumb for separating "substantial" and "insubstantial" portions of the OSM database. Sure, there are exceptions, but I expect they'll mostly be in the direction of larger extracts still being insubstantial. -- Mark _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
