**transportation** containsrRoads and railways.
|
|
This layer is directly derived from the OSM road hierarchy which is why it is called `highway`. Only
|
|
at zoom level 4 to 7 some major highways from Natural Earth are used otherwise it is only OSM data.
|
|
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. If you can put enough effort into it
|
|
makes sense to carefully style each `subclass`. For more comfortable styling you can also just style the roads
|
|
by `class`. Roads can have different properties, a road can have `oneway=yes` and `bridge=yes` at the same time.
|
|
These properties are reflected in the field `properties`.
|
|
This layer is not meant for labelling the roads (the purpose of the layer `highway_name`).
|
|
|
|
The `highway` layer also contains polygons for things like plazas.
