NAME
v.net.allocDESCRIPTION
v.net.alloc allocates subnets for nearest centres (direction from centre). Centre node must be opened (costs >= 0). Costs of centre node are used in calculation. Supported are cost assignments for both arcs and nodes, and also different in both directions of a vector line. For areas cost will be calculated along boundary lines.NOTES
Center nodes have to be assigned to vector nodes using v.digit. Nodes and arcs can be closed using cost = -1.EXAMPLE
# nlayer=1 if no extra table for nodes:
v.net.alloc network out=network_alloc ccats=0-13 nlayer=1
# the result has to be selected by category number of the relevant node:
d.vect network_alloc cat=9 col=red
d.vect network_alloc cat=11 col=green
d.vect network_alloc cat=2492 col=yellow
