momepy.mean_node_degree

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

Calculates mean node degree for subgraph around each node.

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:
graph : networkx.Graph

Graph representing street network. Ideally genereated from GeoDataFrame using momepy.gdf_to_nx()

radius: int

radius defining the extent of subgraph

name : str, optional

calculated attribute name

degree : str

name of attribute of node degree (momepy.node_degree())

distance : str, 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.

Returns:
Graph

networkx.Graph

Examples

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