description: |

|
Roads or [`highway`](http://wiki.openstreetmap.org/wiki/Key:highway) in OpenStreetMap lingo.
|
|
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.

fields:
|
|
class: |
|
|
Either `motorway`, `major_road` (containing `trunk`, `primary`, `secondary` and `tertiary` roads) and `minor_road` (less important roads in the hierarchy like `residential` or `service`) or `path` for
|
|
non vehicle paths (such as `cycleway` or `footpath`).
|
|
subclass: |
|
|
Original value of the [`highway`](http://wiki.openstreetmap.org/wiki/Key:highway) tag. Use this to do more
|
|
precise styling.
|
|
properties: |
|
|
Additional properties describing the nature of road.
|
|
The properties `bridge` and `tunnel` can be combined with `oneway` as well. So to style all bridges the same you
|
|
should style both the properties `bridge` and `bridge:oneway`.
|
|
Properties can be one of `bridge:oneway`, `tunnel:oneway`, `ramp`, `ford`, `bridge`, `tunnel` or`oneway`.
