Preparing a Patchworks Road Network

A two part process is used to create a model of existing and potential road access. The first step involves pre-processing the spatial road files that describe all the existing and future potential road segments, along with the associated cost information. The second step involves spatially linking the road files to the block dataset, and converting the resulting data in to the required Patchworks file formats. The foundation of the Patchworks road model is a shapefile or coverage of the existing road line work for the management area. Pre-processing of the existing spatial route information usually involves three steps:

  1. Simplification

  2. Densification

  3. Attribute addition
