## NAME

v.net.bridge

## DESCRIPTION

v.net.bridge finds bridges and articulation points in a network.

## NOTES

Bridge 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. If method=bridge then lines corresponding to bridges are copied from the input map to the output map. On the other hand, if method=articulation then point are created on the positions of articulation points.
In GRASS, line is not always a single line segments. 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.
