momepy.mean_node_degree¶

momepy.mean_node_degree(graph, radius=5, name='mean_nd', degree='degree', distance=None, verbose=True)[source]¶

Calculates mean node degree 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.

Parameters

graphnetworkx.Graph: Graph representing street network. Ideally generated from GeoDataFrame using momepy.gdf_to_nx()
radius: int: radius defining the extent of subgraph
namestr, optional: calculated attribute name
degreestr: name of attribute of node degree (momepy.node_degree())
distancestr, optional: Use specified edge data key as distance. For example, setting distance=’weight’ will use the edge weight to measure the distance from the node n.
verbosebool (default True): if True, shows progress bars in loops and indication of steps

Returns

Graph: networkx.Graph if radius is set
float: mean node degree for graph if radius=None

Examples

>>> network_graph = mm.mean_node_degree(network_graph, radius=3)
