Hello all, After I've got my v.net.distance up and running I have to adjust my analysis method to the software's capabilities. Basically, I have a 3 layered network: myroads_net2 which contain layers as follow:
Layer 1: Arch (roads) Layer 2: Points (Landfills - destinations) Layer 3: Points (Settlements - source) As one might understood I'm trying to calculate the lowest cost route between each settlement (layer 3) to each landfill (layer 2). Roads' costs are constant, which now set to 1 (currency per distance unit - I guess that it is meter). I would like to include a cost for landfill (gate fee) which will be measured with the same currency. MY attempt to use ncolumn (cost for nodes) didn't go well. I have opened a new column (double precision) in layer 2 and named it gatefee. I have assigned 0 to all cats, except cat=3 which I have assigned with 60. My expectation was that at least some of the settlements that were allocated to cat=3 on layer 2 will be allocated to another one. However after running v.net.distance again with ncolumn=gatefee I have found out that more settlements were allocated to cat=3 of layer 2. Did I misused that option? I can't find any guide to how to use it in the manual or tutorials and will appreciate an explanation or a reference to such guide or tutorial. Best, Dor
