OpenStreetMap [waterways](https://wiki.openstreetmap.org/wiki/Waterways) for higher zoom levels (z9 and more)
|
|
and Natural Earth rivers and lake centerlines for low zoom levels (z3 - z8).
|
|
Linestrings without a name or which are too short are filtered
|
|
out at low zoom levels.
|
|
Till z11 there is `river` class only, in z12 there is also `canal` generated,
|
|
starting z13 there is no generalization according to `class` field applied.
|
|
Waterways do not have a `subclass` field.

name: |
|
|
The OSM [`name`](http://wiki.openstreetmap.org/wiki/Key:name) value of the waterway. Language-specific values are in `name:xx`.
|
|
The `name` field may be empty for NaturalEarth data or at lower zoom levels.
|
|
name_en: English name `name:en` if available, otherwise `name`. This is deprecated and will be removed in a future release in favor of `name:en`.
|
|
name_de: German name `name:de` if available, otherwise `name` or `name:en`. This is deprecated and will be removed in a future release in favor of `name:de`.
