Important notes:
- This key has never been really discussed publicly. This thread on the tagging mailing list suggests to deprecate these landmark tags when it's already existing and use instead a generic "maritime_landmark=yes". For instance, instead of "landuse=cemetery" + "landmark=cemetery", use "landuse=cemetery" + "maritime_landmark=yes". --Pieren 18:08, 30 December 2012 (UTC)
- Note that maritime_landmark=yes is also undiscused and unused.
- Since established seamark tagging scheme there is seamark:type=landmark; see also Seamarks/Landmarks. --Chris2map 8 January 2023

Landmarks
It was proposed to tag every nautical landmark with seamark=landmark + landmark=*
The S57-catalog differs between a bunch of useful landmarks we should use in landmark=* at least:
Many of these have its own dedicated INT 1 symbol for rendering on nautical maps
