|Feature : Marine navigation|
|Mapping for marine navigation|
Marine navigation explains how to map the many natural and man-made features associated with the safe movement of ships and boats on the sea. See Marine for details about more general features of the marine environment and Coastline for details about how to tag features found along and close to the shore. Waterways provides information about navigation of inland waterways.
- See also: Coastline
The coastline is a rich and complex environment consisting of many natural and man-made features. Tags relevant to marine navigation include man_made=beacon, natural=coastline, man_made=lighthouse, natural=peak, amenity=place_of_worship, man_made=tower, man_made=gasometer, man_made=windmill and wind generators (power=generator + generator:source=*).
Harbours, marinas and anchorages
- See also: Harbour
Harbours, used by ferries and commercial shipping should be mapped using a node tagged with harbour=yes and the area of land used to support the harbour should be tagged as an area using landuse=harbour. Marinas, used by pleasure boats and yachts should be tagged with leisure=marina. Naval bases should be tagged with military=naval_base. Piers against which boats can be moored should be tagged as (man_made=pier) together with mooring=yes/ferry/etc.
Ferry and shipping routes

seamark:type=* is used for a wide variety of shipping markers, including:
- seamark:type=light_major for lights visible for many miles
- seamark:type=light_minor for smaller lights
- seamark:type=beacon_lateral for a beacon marking the port or starboard limits of a navigable channel.
- seamark:type=buoy_lateral for a buoy marking the port or starboard limits of a navigable channel.
- seamark:type=beacon_cardinal A beacon marking a hazard, indicating the compass quadrant for safe passage
- seamark:type=buoy_cardinal A buoy marking a hazard, indicating the compass quadrant for safe passage
- seamark:type=light_vessel A light vessel
These tags are examples from a larger set, details of which can be found here: Seamark Tag Values
The OpenSeaMap project provides marine navigation mapping based on these tags.
- LOCODE covers 60,000 locations in 242 countries and 1000 regions. Among other things it is used to identify international seaports. The local-code consists of 5 characters. The first 2 descibe the country (ISO-3166-1) the last 3 following the location of the harbour.
- World Port Index contains 4300 harbours in 400 regions. Every harbour has a 5-digit number as index.
