"seamark:" is a Namespace that indicates a feature defined by IHO. IHO is the international organisation responsible for nautical chart standards.

Tags of the form "seamark=..." are not part of this namespace (however, the tags seamark=buoy and seamark=beacon have been used several thousand times).

All nautical objects tagged within the "seamark:" namespace must include a seamark:type=* tag, which indicates a particular navigational feature that is used in sea charts. For rendering in nautical charts, this tag must be used to indicate the principal symbol to be displayed.

For further information, see:


See seamark:type=*
