Operator), and by creating new lines between pairs of vector pointsĪ GIS network consists of topologically correct lines (arcs). Intersections in a map of vector lines ( node operator), byĬonnecting a vector lines map with a points map ( connect ) and points ( nodes) by creating nodes from Main use is to create a vector network from vector lines ( arcs Generating network with turntable for vector point mapĭESCRIPTION v.net is used for network preparation and maintenance.Generating network for vector point map.Merge in nodes from a separate map within given threshold.Create nodes globally for all line ends and intersections.Default: 3 turn_cat_layer= string Layer with unique categories used in turntable Layer with unique categories for every line in arc_layer and point on every node. Format: layer number.Required for operation 'turntable'. file= name Name of input file Required for operation 'arcs' ('-' for standard input) turn_layer= string Turntable layer Layer where turntable will be attached. Default: 2 threshold= float Threshold Required for operation 'connect'. When used with direct OGR access this is the layer name. This number determines which layer to use. Default: 1 arc_type= string Arc type Input feature type Options: line, boundary Default: line,boundary node_layer= string Node layer Vector features can have category values in different layers. Parameters: input= name Name of input vector line map (arcs) Required for operation 'nodes', 'connect', 'report' and 'nreport' points= name Name of input vector point map (nodes) Required for operation 'connect' and 'arcs' output= name Name for output vector map operation= string Operation to be performed Options: nodes, connect, arcs, report, nreport, turntable nodes: new point is placed on each node (line end) if doesn't exist connect: connect still unconnected points to vector network by inserting new line(s) arcs: new line is created from start point to end point report: print to standard output turntable: create turntable on vector network arc_layer= string Arc layer Vector features can have category values in different layers.
