Properties

Field Type Label Description
partition​_​name string  

Quadkey (HERE tiling) for the current partition.

node​_​anchor Node​Anchor repeated

All unique node anchors in this partition. Referenced by 0-based index.

segment​_​anchor Segment​Anchor repeated

All unique segment anchors in this partition. Referenced by 0-based index.

curvature​_​heading Curvature​Heading​Attribute repeated

Curvature is an approximation of the road geometry by means of circles at road geometry points (Nodes or Shape Points). Heading is the direction toward which a road is oriented.

elevation Elevation​Attribute repeated

Elevation is the measure of the height value of a point on the Earth’s surface with reference to the mean-sea level.

slope Slope​Attribute repeated

Slope is the angle of inclination at a Shape Point when traversed from Reference to Non-Reference node, or at a Node indicating the angle of inclination from this Node toward the segment.

built​_​up​_​area​_​road Built​Up​Area​Road​Attribute repeated

Built-up Area Road is a Functional Class (Level 5) road within smaller Built-up Areas that have the legal yellow Built-up Area sign. These are not found worldwide but are found only in specific countries.

link​_​accuracy Link​Accuracy​Attribute repeated

Link Accuracy indicates if the geometry associated with a segment meets specific height, slope or positional accuracy.
