Description

The GIS-Lab has an (experimental?) RoadGraph plugin, which makes it possible to calculate shortest or fastes route between to points in a road (or other) network.

It would be nice to see more work on this like:

  • Defining your own utility function to minimize (not just time or distance)
  • Possibility to calculate shortest paths for a set of points - perhaps from a point shape layer with target and/or starting points?
  • Perhaps even calculate a travel time/distance/etc. matrix between all points in the point shape layer (I know processing time will rise!)

Hello, bug triage...

with QGIS 2.13 (and previous versions) we have a Network Analysis library (with Python bindings) and it could be interesting to build new Processing algorithms with it.
For network analysis, I use mainly GRASS and I think it could be also very interesting to add the v.net algorithms in QGIS (perhaps something easier).
