description: |
|
|
This is the layer for labelling the highways. Only highways that are named `name=*` and are long enough
|
|
to place text upon appear. The OSM roads are stitched together if they contain the same name
|
|
to have better label placement than having many small linestrings.
|
|
For motorways you should use the `ref` field to label them while for other roads you should use `name`.

fields:
|
|
name: The OSM [`name`](http://wiki.openstreetmap.org/wiki/Highways#Names_and_references) value of the highway.
|
|
ref: The OSM [`ref`](http://wiki.openstreetmap.org/wiki/Key:ref) tag of the motorway or road.
|
|
ref_length: Length of the `ref` field. Useful for having a shield icon as background for labeling motorways.
|
|
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.
