|Tools for this tag|
The tag natural=atoll is used to map an atoll (sometimes called a coral atoll), a ring-shaped coral reef including a coral rim that encircles a lagoon partially or completely, and may include small islands or islets.
How to map
- Note: place=island must be use the coastline when mapped as an area or relation, but natural=atoll should include the entire area of the coral reef and lagoon, in addition to any island or islets.
- Consider adding the islands to a multipolygon relation with place=archipelago if the group of islands has a name.
