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`.

description: |
|

The `railway` layer contains linestrings marking tracks from [OSM Railways](http://wiki.openstreetmap.org/wiki/Railways).
|
||||
It contains tracks for [passenger and freight trains]() and smaller tracks for [Trams](http://wiki.openstreetmap.org/wiki/Tag:railway%3Dtram) or [similar](http://wiki.openstreetmap.org/wiki/Tag:railway%3Dlight_rail) vehicles. But also tracks for [subways](http://wiki.openstreetmap.org/wiki/Tag:railway%3Dsubway), [narrow-gauge trains](http://wiki.openstreetmap.org/wiki/Tag:railway%3Dnarrow_gauge) or [historic trains](http://wiki.openstreetmap.org/wiki/Tag:railway%3Dpreserved).
|
||||
Non mainline tracks (marked with class `minor_rail`) used for [storage of trains](http://wiki.openstreetmap.org/wiki/Tag:service%3Dyard) and [maintenance](http://wiki.openstreetmap.org/wiki/Tag:service%3Dsiding) are contained in the highest zoom levels and should be styled more subtle than the mainline tracks with class `rail`.
|
||||
fields:
|
||||
class: |
|
||||
Divides the track into mainline tracks (class `rail`) and less important tracks
|
||||
used for maintenance (class `minor_rail`).
|
||||
subclass: |
|
||||
Original value of the [`railway`](http://wiki.openstreetmap.org/wiki/Key:railway) can be one of
|
||||
`rail`, `light_rail`, `subway`, `narrow_gauge`, `preserved`, `tram`.
|

Additional properties describing the nature of tracks. Can be either `bridge` or `tunnel`.

**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.
