I'm looking to measure the distance from postcode centroids (point file) in a city to the nearest bus stop (point file) along the road network (line file).
In QGIS I can calculate the distance but it is not measured along the road network. I'm sure this can be performed in GRASS GIS however, but unsure to how (v.distance maybe). Its the
to part of the v.distance code I'm struggling with, as I can't find where to specify along the network, or does all three files need to be connected to each other and in different layers?.
