description: |
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.
