Lake center lines for labelling lake bodies.
|
||
|
|
This is based of the [osm-lakelines](https://github.com/openmaptiles/osm-lakelines) project
|
||
|
|
which derives nice centerlines from OSM water bodies. Only the most important lakes contain labels.
|
||
|
|
fields:
|
||
|
|
name: The OSM [`name`](http://wiki.openstreetmap.org/wiki/Key:name) value of the water body. Language-specific values are in `name:xx`.
|
||
|
|
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`.
