    Description

    A roadrunner.hdmap.Metadata object enables you to describe elements in a RoadRunner HD Map scene model by adding user-defined ancillary data. You can specify the name of a user-defined parameter and set its value.

    Creation

    Syntax

    metadata = roadrunner.hdmap.Metadata
    metadata = roadrunner.hdmap.Metadata(Name=Value)

    Description

    metadata = roadrunner.hdmap.Metadata creates an empty metadata object.

    example

    metadata = roadrunner.hdmap.Metadata(Name=Value) sets properties using one or more name-value arguments.

    Create an empty RoadRunner HD Map by using the roadrunnerHDMap object. Notice that the map does not have any lanes.

    rrMap = roadrunnerHDMap
    rrMap = 
  roadrunnerHDMap with properties:

    Define metadata for a lane using the roadrunner.hdmap.Metadata object.

    metadata = roadrunner.hdmap.Metadata(Name="Name",Value="Left Shoulder Lane");

    Create a lane using the roadrunner.hdmap.Lane object. Specify the lane ID, lane geometry, travel direction, lane type, and metadata attributes for the lane.

    rLane = roadrunner.hdmap.Lane(ID="Lane1", ...
    Geometry=[-0.782 -1.56;50.78 23.43], ...
    TravelDirection="Forward", ...
    LaneType="Driving", ...
    Metadata=metadata);

    Add the lane to the RoadRunner HD Map.

    rrMap.Lanes = rLane
    rrMap = 
  roadrunnerHDMap with properties:
