Road network data model

The Patchworks road network model is described through a series of road segment end points (nodes) and multi-point lines connecting pairs of nodes that represent the road segments. Linkages describe how each block is connected to the closest node, and wood product destinations (mills) are located at nodes in the network. Patchworks will automatically connect wood products from stump to mills through the network in order to satisfy the active suite of targets, making the routing model extremely flexible and adaptable.

To explore the road network data model we will first examine these files to see what each contains and how they relate to one another. This information can then be used to explore the larger picture of a complete and comprehensive road network capable of modelling various road construction and access scenarios based on wood flow, accessibility and economics. Next we will work through an example looking at the data values for a simple network.
