Road Labels (Optional)

This is an optional layer, and its content is defined as follows.

• Layer name: road_labels
• Geometry types: line

This layer contains deduplicated labeling properties (name, ref, network, shield_text) and simplified label placement geometry for all kinds of transportation, including but not limited to highways, major roads, minor roads, paths and ferries, which are present in the roads layer.

In the roads layer, each road segment contains labeling properties, which could be the same (and there are a lot of them) for consecutive road segments. To remove such duplicates and avoid post processing on the client side, the road_labels layer stores already merged and simplified consecutive road segments with the same name properties. However, you still can decide which layer (roads or road_labels) best suits your special needs as a source of labeling properties.

Road Label Properties (common)

• name - Generally the name the locals call the feature, in the local language script.
• ref - A commonly used reference for roads - for example, "I 90" for Interstate 90. To use with shields, see the network and shield_text properties.
• network - This property is useful for shields and road selections - for example, US:I for the United States Interstate network. It contains only road network types. For more information, see a full list of possible road network values.
• shield_text - This property contains the text to display on a shield. For example, I 90 would have a network of US:I and a shield_text of 90. The ref value, I 90, is less useful for shield display without further processing. For some roads, this property can include non-numeric characters - for example, the M1 motorway in the UK has a shield_text value of M1, rather than just 1.
• all_route_types - All the route types of which this road is a part. This is given as semicolon-separated numeric codes used for shield styling depending on the country.
