Status: de facto

Use the man_made=groyne tag to mark a groyne, which is a rigid structure stretching out a short distance from the shoreline or riverbank for the purpose of reducing the movement of sediment (eg sand and gravel) or sometimes to reduce ice-jamming.

Not to be confused with man_made=breakwater, which is used for structures designed primarily to create an area of calm water for mooring boats, or with man_made=pier, which is used for structures on which people walk over water to access boats or similar.


How to map

See also Coastline

Create a linear way along the length of the groyne. Alternatively create a sequence of linked ways with one or more additional tags. For example:

  • submerged=yes - for the part always submerged
  • tidal=yes - for the part that are submerged on high tide and above water on low tide
  • height=* - height over seabed (question: is the height not variable along its length? PeterIto 20:01, 23 August 2012 (BST))

Very wide groynes (such as https://www.openstreetmap.org/way/373881874) can be mapped as areas.
