DESCRIPTIONv.net.bridge finds bridges and articulation points in a network.NOTESBridge in a network is an edge/line whose removal would disconnect the (sub-)network. A node is an articulation point if its removal would disconnect the (sub-)network. For more information and formal definitions check the wikipedia entries: bridge and articulation point.The output of the module contains the selected features. For method=bridge, lines corresponding to bridges are copied from the input map to the output map. On the other hand, for method=articulation, points are created on the positions of articulation points. In GRASS GIS, line is not always a single line segment. It might be, and often is, a sequence of line segments between two intersections. Also, articulation point is a standard graph theoretic terminology which is slightly misleading in GRASS. An articulation point in graph theory is an articulation node in GRASS terminology.
