Water polygons representing oceans and lakes. Covered watered areas are excluded (covered=yes). On low zoom levels all water originates from Natural Earth. To get a more correct display of the south pole you should also style the covering ice shelves over the water. On higher zoom levels water polygons from OpenStreetMapData are used. The polygons are split into many smaller polygons to improve rendering performance. This however can lead to less rendering options in clients since these boundaries show up. So you might not be able to use border styling for ocean water features.



From zoom 6 are taken OSM IDs. Up to zoom 5 there are used Natural Earth lakes, where are propagated the OSM IDs insted of Natural Earth IDs. For smaller area then planet, NE lakes keep their Natural Earth IDs.


All water polygons from OpenStreetMapData have the class ocean. Water bodies with the water=river tag are classified as river. Wet and dry docks tagged waterway=dock are classified as a dock. Swimming pools tagged leisure=swimming_pool are classified as a swimming_pool All other water bodies are classified as lake.

  • dock

  • ocean
  • swimming_pool
