v.net.connectivity computes vertex connectivity between two sets. i.e., minimum number of vertices whose removal would separate two given sets.
NOTES
Two sets (set1 and set2) are specified by respective layer, where and cats parameters. Similarly to v.net.flow module, capacities of nodes can be given by ncolumn option. Module finds the set of nodes of minimum total capacitiy separating the two given sets and outputs map containing points on the positions of these nodes. Default capacity, which is used when no column is specified, is one.
EXAMPLES
The following command finds the minimum number of intersection separating roads on the left bank from roads on the right bank.
