Chapter 6. Network Analysis
In this chapter, we will cover the following recipes:
- Creating a simple routing network
- Calculating the shortest paths using the Road graph plugin
- Routing with one-way streets in the Road graph plugin
- Calculating the shortest paths with the QGIS network analysis library
- Routing point sequences
- Automating multiple route computation using batch processing
- Matching points to the nearest line
- Creating a network for pgRouting
- Visualizing the pgRouting results in QGIS
- Using the pgRoutingLayer plugin for convenience
- Getting network data from the OSM
Introduction
This chapter focuses on the common use cases that are related to routing within networks. By far, the most common networks that are used to route are street networks. Other less common cases include networks for indoor routing, that is, through rooms inside buildings, or networks of shipping routes.
Networks and routing are in no way a GIS-only topic. You will find a lot of math literature related to this, called...
