maritime=yes is used in two ways:

For boundaries: Approved

To indicate a maritime administrative boundary, see boundary=maritime for more details on maritime boundary tagging. According to this approved proposal, maritime=yes was originally designed for tagging the 12 nautical miles territorial sea limit. Practically it is also used for all administrative boundaries that are located outside the coastline independent of their function and admin_level=*, such as province, State, county or district boundaries that are outside of the coastline or in the middle of a marine water body.

As of May 2019, the tag maritime=yes has been used 9 434 times. It is used in combination with boundary=* 8 586 times (91%) and with admin_level=* 8145 times (86%).

How to Map: Boundaries

  • Add this tag to the ways of an administrative boundary which are located outside of the coastline.

For water areas: In Use

To indicate a water area (tagged waterway=riverbank or natural=water + water=river ) belongs to the maritime domain, i.e. it is connected to the ocean and ocean currents regularly lead to water transport in both directions. The meaning here is similar to tidal=yes but applies also in areas with little or no tides.

This usage is less common and was not part of the Maritime boundaries proposal. As of May 2019, maritime=yes has been used with natural=* a total of 108 times, and with waterway=* 51 times, according to Taginfo

How to Map: Marine rivers

  • Add this tag to the areas (closed ways or multipolygons) of a river estuary which are part of the marine environment
  • This tag is often added to areas of water which are considered rivers by locals but which could also be considered part of the sea.
