HERE Lanes Release Notes

Limitations

HERE Lanes Native (Production Catalogs)

This section documents limitations that affect applications and/or map data related to HERE Lanes Native in Production Catalogs.

  • This HERE Lanes catalog includes some lane attributes and/or schemas from HD Live Map that are out of scope for the HERE Lanes product definition. They will be filtered out in a later release:
    • Lane Boundary Marking Lateral Offset
    • Lane Boundary Marking Material
    • Lane Boundary Marking Width
    • Lane Adjacency
    • Lane Stopping Location
  • For certain attributes, only the schema is available, but no data; see list above.
  • Specification Compliance Identifier definitions will likely change in the future as we further evolve the HERE Lanes Product.
  • Lane Access Characteristics are assigned only on a subset of the Spec 1 coverage on Limited Access roads.
  • Lane Boundary Marking Style:
    • Spec 1: Solid, Dashed, Alternate Dashed; double markings.
    • Spec 4: Solid, Dashed; double markings.
    • Autogenerated content: Solid, Dashed, Alternate Dashed (if available in SD Map); double lane markings (if available in SD Map); no lane markings in intersections.
  • Lane Speed Limit: Assigned on only a subset of the Spec 1 coverage on Limited Access roads.
  • Lane Type:
    • Lane Type "Bus" is not included
    • Inclusion for other Lane Types:
      • Spec 1: All types except Bus on a subset of the scope. On the remaining scope: Drivable Shoulder, HOV, Regular (if other lane types are present), Other, Unknown; other lane types if available from auto-generated content.
      • Spec 4: Bicycle, HOV, Reversible, Regular (if other lane types are present), Other, Unknown; other lane types if available from autogenerated content.
      • Autogenerated content: All types if available in SD Map; no lane types in intersections.
  • Road Boundary Type: Only type "Gore" is included with limited coverage and quality. This attribute is under evaluation for future inclusion.
  • Lane Boundary Traversal is based on Lane Boundary Marking Style. In the future, additional logic is targeted to be implemented for:
    • Specific Lane Types like Drivable Shoulder Lanes and Center Turn Lanes
    • Non-Drivable Lanes and Medians
    • Lanes with an opposite travel direction

HD Live Map Viewer

The CIT HDLM Viewer is available for basic coverage and feature visualization of HERE Lanes content. However there are currently some limitations:

  • Visualization of some new HERE Lanes features (e.g. Road Surface Markings) is not supported. However, the textual representation of all lane attribution is visible in the "All Lane Details" panel.
  • The "HAD Compliance" overview is not currently available for HERE Lanes, but will be supported in an upcoming update.
  • Only the "Layer Data Sizes" tab of the Product Statistics view is supported for HERE Lanes. Attribution statistics will be added in an upcoming update.
