highway_name

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

• ref: The OSM 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.
• name: The OSM name value of the highway.
• subclass: Original value of the highway tag. Use this to do more precise styling.
• 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).
