[Qgis-developer] Help make graph from line vector shapefile

[pcreso at pcreso.com]

Look at pgRouting in Postgis, for a possible back end to this. I know of one web app that sit on top of this for shortest path apps, with output maps showing the results.

Hi,  I'm a new QGIS developer. I want to create a graph, a network, with a vector line layer that represents the roads of a city, to find the shortest path between two points.Can you help me to transform the vector layer in a graph, or split the lines features of the layer in the in-node and out-node?How I have to use the qgis.core library, in particularly, the QgsGraph class?  Greeting,raffalba
