meshedness
(graph, radius=5, name='meshedness', distance=None)[source]¶ Calculates meshedness for subgraph around each node if radius is set, or for whole graph, if
radius=None
.Subgraph is generated around each node within set radius. If
distance=None
, radius will define topological distance, otherwise it uses values in distance attribute.\[\alpha=\frac{ev+1}{2 v5}\]where \(e\) is the number of edges in subgraph and \(v\) is the number of nodes in subgraph.
Adapted from [Fel18].
 Parameters
 graphnetworkx.Graph
Graph representing street network. Ideally generated from GeoDataFrame using
momepy.gdf_to_nx()
 radius: int, optional
Include all neighbors of distance <= radius from n
 namestr, optional
calculated attribute name
 distancestr, optional
Use specified edge data key as distance. For example, setting
distance=’weight’
will use the edgeweight
to measure the distance from the node n.
 Returns
 Graph
networkx.Graph if radius is set
 float
meshedness for graph if
radius=None
Examples
>>> network_graph = mm.meshedness(network_graph, radius=800, distance='edge_length')
