Nature and land
The land of the island
Woodland or shrubland 50%, Water 45%, Open/natural land (grassland, bare ground) 5%.
Source: ESA WorldCover 2021, a 10 m satellite classification generalised to a ~1 km grid and counted inside the island's outline. Shares are rounded to 5% and describe what covers the ground, not land use or building rights. On small islands the grid is coarse and coastal cells may read as water.
How the numbers were counted
The island is a place=island outline in OpenStreetMap and its area is computed from it. Settlements, beaches, airports and ports belong to the island when their point lies inside the outline (or, for beaches and ports, up to 250 to 500 m outside it).
A municipality counts as being on the island when its seat or main town is there, or when at least half of its settlements are. A port is a group of ferry terminals mapped in OpenStreetMap within 1 km of each other; the name is the nearest settlement.
The page exists because the island has a city, town or village (or a hamlet with an official bathing-water site or a ferry port) and at least two of: an official bathing-water site, a port or airport, a settlement with a page of its own, a Wikidata item.
