I have a given road network dataset as polylines and want to create a network out it. For that, I found
v.net from the GRASS GIS toolbox.
Now (1) I'd like to get the OD matrix from the intersections computed by the given shape length. I think this is the simplest possible solution to get all the distances. Due to my very big network, I'd like (2) also to limit the spatial computational space for the network, that the distance is just computed for a certain number of nodes. Afterwards, the distance is already Infinity.
Is there a way to achieve my goal in QGIS?
