I mentioned a few posts back that there was a great resource for
downloading OpenStreetMap data, and that it was relatively easy to
import osm data into PostgreSQL/PostGIS for use with pgRouting to
calculate shortest paths and various other network-based operations. In
this post, I’ll outline the steps required to get all this up and going,
and provide a quick example to show how this can be combined with QGIS
to visualise the computed shortest path directly.
