[pgrouting-users] Possible to use pgrouting for "layered" data?

[Daniel Kastl]

You can try it out here: http://plan.epfl.ch/
The "campus routing" also allows to set "disabled" flag for those, who can't
use stairs for example.
I think the application is a bit difficult to use if you don't know room
numbers. You can input the building ID for example, but this obviously won't
route you between floors.

In general pgRouting can handle different levels when you model your network
right.
You need to add links between the different levels and assign costs.
