An island is any piece of land that is completely surrounded by water and isolated from other significant landmasses.
How to map
Island in the sea
Draw a closed way counterclockwise along the coastline of the island (water is always on the right hand side). Then add the tags:
Island in waterway or lake
Island within lakes or rivers should be mapped using multipolygon relations. Multipolygon representing water will have a following topology:
- The way for the shore of island (inner border of water) should be given the role inner
- The way for shore lake or river (outer border of water) should have the role outer.
if an island is in the middle of the sea and far away of other islands, it may be tagged as "island". Example:
Group of islands
Submerged sometime or all time
Consider using natural=bare_rock/rock/sand/shoal + tidal=yes, or natural=wetland + wetland=tidalflat for area that only emerge from water during low ride, and use natural=reef or subsea=* for area that always stay below water surface. was:place=island/islet might be useful in indicating features that used to be an island but is no longer an island now, so as to avoid mistagging by other contributors.
If you place an island on dry land, do not expect water to automatically appear around the island.
You need to map water area.
Adding this tag to an island will place an italicized label on it.
The openstreetmap.org Standard layer uses a different method to render coastlines. It takes up to a day before changes to the coastline are seen in the tiles. For more details, see Coastline.
