WebMay 14, 2024 · A high betweenness centrality value indicates a critical role in network connectivity. Because there are currently no Centrality tools in ArcGIS, I created a simple ArcGIS Pro 2.1 GP toolbox that uses the NetworkX Python library to make these types of analyses easy to incorporate in ArcGIS workflows. Centrality Analysis Tools WebBetweenness centrality finds wide application in network theory; it represents the degree to which nodes stand between each other. For example, in a telecommunications network, a node with higher betweenness centrality would have more control over the network, because more information will pass through that node.

WebApr 13, 2024 · Edge Betweenness Centrality (EBC) The edge betweenness centrality (EBC) can be defined as the number of shortest paths that pass through an edge in a network. Each and every edge is given an EBC score based on the shortest paths among all the nodes in the graph. WebParameters-----G : NetworkX graph most_valuable_edge : function Function that takes a graph as input and outputs an edge. The edge returned by this function will be recomputed and removed at each iteration of the algorithm. If not specified, the edge with the highest:func:`networkx.edge_betweenness_centrality` will be used.
