Summary
A reef is an area of sea bed which can be made from rock or possibly a sandbar. It is usually just beneath the surface and may be exposed at low tide levels.
Wikipedia provides a detailed explanation of a reef [1]
Reasoning
There is currently no suitable tag for a reef. Reefs are popular destinations for diving/snorkelling. They frequently pose a hazard to shipping/marine activities.
How to Map
Example & Description
The Great Barrier Reef is famous throughout the world as an area of natural beauty. Popular with tourists, divers and marine biologists, it is currently completely unmapped. See [2] and click on edit to see one area that is unmapped.
Another example here [3]. Again click edit to see what is missing.
Extended Usage
Could also add:
- type=coral
- type=oyster
- type=fringing - Where the reef is attached to an island.
- type=barrier - Where the reef forms a barrier near an island leaving an area of water between the shore and the reef.
- depth=number - The depth of water above the reef at lowest tide. So if number is 0, the reef is uncovered at low tide.
- artificial=yes|no - If the reef is natural or from a sunken ship for example. artificial=no is assumed if tag omitted.
Rendering could be different for various types and also if depth=0. Note: Parts of a reef that are never covered by water should be considered as land and tagged appropriately.
Alternate Name Suggestions?
- subsea=* - currently ~ 1000 coral reefs mapped that way
- sub_sea=* - currently ~ 600 coral reefs mapped that way
