Hi list, I'm beginning to learn and use the v.net tools in Grass in order to evaluate the distance from several crop fields to a processing plant.
I've successfully build the road network with the end nodes but now I'm in doubt. My starting points in the analysis are crop fields, which are polygons. So what is the best (or most common) practice? 1) Use the field centroids as starting nodes? 2) Add field polygon boundaries to the network and run v.net.distance backwards (from mill to fields)? 3) Some other option? Also, if I'm to add the field boundaries to the network, how would I go about it? Should I first v.patch the field with the roads layer and then run v.net? Thanks Daniel
