pgRouting is an extension that builds on PostGIS for performing network routing such as road navigation, hiking, and other things.
In this talk we'll give a crash course of what you can do with pgRouting with a special focus on pgRouting 2.1, and time permitting, highlights of upcoming pgRouting 2.2.
Coverage will detail:
1) Making general data routable and applying costs to data
2) Using dijkstra to determine optimal paths from one start location to one destination
or for choice travel options - one source to many destinations
3) Finding multiple paths solutions given a start and end point
Given a starting point and desired end point, what are the N least costly solutions to the problem using K-Shortest Path (KSP).
Gotchas you should watch for when using this. (K-Shortest Path (KSP) )
4) Viewing your solutions in QGIS
