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
- The following roads do not include lanes:
- Walkways and Pedestrian Roads
- Bicycle Paths
- Ferries
- Parking Lot Roads
- The following roads might include lanes: Alleys
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.
