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](http://osmdata.openstreetmap.de/) 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.

All water polygons from [OpenStreetMapData](http://osmdata.openstreetmap.de/) have the class `ocean`.

Water bodies with the [`waterway=riverbank`](http://wiki.openstreetmap.org/wiki/Tag:waterway=riverbank)
|
|
or [`water=river`](http://wiki.openstreetmap.org/wiki/Tag:water=river) tag are classified as river. Wet and dry docks
|
|
tagged [`waterway=dock`](http://wiki.openstreetmap.org/wiki/Tag:waterway=dock) are classified as a `dock`.
|

All other water bodies are classified as `lake`.
