Land area in km²: the Largest Islands set’s figure for its islands, else Wikidata’s (P2046) where it fits the outline, else the area of the outline. Every island Natural Earth draws at 1:10m that Wikidata names, of 5 km² or more (smaller ones when well known), and every island of the Largest Islands set. Countries are those the island’s land lies in, from the outlines. An item counts for every first-level unit (state, province, county) it touches: a lake or island by its outline, a river by its course, within about 1.5 km; a summit, a cape or anything without a shape by its point.
