The Topology Geometry layer contains the definition of the intersection to intersection road model, expressed as connected graph of segments and nodes. It also includes the 2D geometry for these segments and nodes.
| ||string|| |
Quadkey (HERE tiling) for the current partition.
| ||Node||repeated|| |
List of nodes located in the partition. Nodes are included in the partition that holds their coordinates. Coordinates are inclusive on the southern and western edges of a partition. Partitions always include their southern and western edges and, with two exceptions, do not include their northern and eastern edges. The two exceptions are: (1) A partition whose eastern edge is 180 degrees east longitude includes the eastern edge; (2) a partition whose northern edge is 90 degree north latitude includes the northern edge.
| ||Segment||repeated|| |
List of segments located in the partition. Segments are included in the tile that contains their start node.
