[Qgis-user] create clean knot-edge-model

[Nicolas Cadieux]

Btw Christoph,

If you have multiple shortest path routes to figure out (as in hundreds, millions, or billions in my case), contact me.  I am working on a python script to do that.

> Snap geometries to layer, (search for snap in processing)
> V.clean (break an snap,rmdangles....) see the cleaning tools.
