Topology reference types for lane attributes

Note: This topic pertains to the Features and attributes topic.

In the Lane Model, attributes reference lanes in the following ways:

• Lane Parametric Range: Applies to the parametric range of a lane, as designated by starting and ending length fractions (i.e., values from 0 to 1) on the associated lane.
• Lane Parametric Point: Applies to a single point along a lane, as designated by as a fractional distance (i.e., values from 0 to 1) from the lane's start.
• Lane Boundary Parametric Range: Applies to the parametric range of a lane boundary, as designated by the starting and ending length fractions (i.e., values from 0 to 1) on the associated lane boundary.
• Lane Group Parametric Range: Applies to the parametric range of a lane group, as designated by the starting and ending length fractions (i.e., values from 0 to 1) of the associated lane group.
