Water polygons representing oceans and lakes. Covered watered areas are excluded (`covered=yes`).
|
|
|
|
|
Until z6 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.
|
|
|
|
|
Water from OpenStreetMap after z7 is 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.
