layer:

|
id: "transportation"
|
|
description: |
|
|
**transportation** contains roads and railways.
|
|
This layer is directly derived from the OSM road hierarchy.
|
|
Only at zoom level 4 to 6 some major highways from Natural Earth
|
|
are used.
|
|
It contains all roads from motorways to primary, secondary and
|
|
tertiary roads to residential roads and
|
|
foot paths. Styling the roads is the most essential part of the map.
|
|
The `highway` layer also contains polygons for things like plazas.
