Description

Mapping the world's oceans and shoreline

Tags

This is a Feature page which provides an introduction to how to map Marine Mapping. To view and contribute to the tagging discussion see the discussion page.

Marine mapping includes adding details about many natural and man-made features along the shoreline and out to sea. It include the mapping of harbours and of ferry and shipping routes as well so the shoreline and sand banks. While great care is often taken adding information to OpenStreetMap the information should be used with caution. See the Openstreetmap:general disclaimer.

Coastline and islands

See also: Coastline, Islands

The coastline in OSM is a rich and complex environment consisting of many natural and man-made features. Tags relevant to marine mapping include natural=beach, man made=beacon, man made=breakwater, natural=cliff, natural=coastline, man made=groyne, man_made=lighthouse and natural=wetland. Other features on land of relevance to navigators include natural=peak, amenity=place of worship, man made=tower, man made=gasometer, man made=windmill, wind generators (power=generator + generator:source=*).

Harbours, marinas and anchorages

see also: Harbour, Marina

Harbours, used by ferries and commercial shipping should be mapped using a node tagged with {{tag|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.

Piers against which boats can be moored should be tagged as (man_made=pier) together with mooring=yes/ferry/etc and, if appropriate floating=yes. Large piers can be tagged using areas.

It is also useful to mark anchorages. One can mark moorings seamark=ACHBRT, depth=* (in meter) and historic=wrecks. It is also useful to record nearby on-shore Amenities.

-- Please add a cleared description of how to actually tag an anchorage. It doesn't say. PeterIto 07:28, 5 February 2012 (UTC)

Navigation aids, including lighthouses, beacons and bouys

lighthouse (touristical)

man_made=lighthouse

Draw a lighthouse as node and check the coordinates with the list of lights. The identification should be tagged as note=*.

Be aware that List of Lights are protected by proprietary licenses, data should never be derived directly from such sources.

Why note=*? Why not ref=*? --Lulu-Ann 10:34, 13 August 2009 (UTC)

For nautical lighthouses please refer to Lighthouse.

For nautical buoys and beacons please refer to Beacon.

Bouys.. See the proposal: Proposed_features/marine-tagging. See an explaination of INT 1 (international rendering standard for marine charts)
