| ||string|| |
Quadkey (HERE tiling) for the current partition.
| ||NodeAnchor||repeated|| |
All unique node anchors in this partition. Referenced by 0-based index.
| ||SegmentAnchor||repeated|| |
All unique segment anchors in this partition. Referenced by 0-based index.
| ||CurvatureHeadingAttribute||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.
| ||ElevationAttribute||repeated|| |
Elevation is the measure of the height value of a point on the Earth’s surface with reference to the mean-sea level.
| ||SlopeAttribute||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.
| ||BuiltUpAreaRoadAttribute||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.
| ||LinkAccuracyAttribute||repeated|| |
Link Accuracy indicates if the geometry associated with a segment meets specific height, slope or positional accuracy.
