dhart.spatialstructures.Graph.AggregateEdgeCosts

Graph.AggregateEdgeCosts(ct: CostAggregationType, directed: bool, cost_type: str = '') → EdgeSumArray

Get an aggregated score for every node in the graph based on

its edges.

Parameters:

• ct – CostAggregationType Aggregation method to use for summarizing edge costs. See CostAggregationType for more information

• directed – bool If false, only consider outgoing edges of each node. If true, consider outgoing and incoming edges.

• cost_type – str Name of the cost set to use for aggregation. If left as blank, will use the default cost of the graph.

Returns:

An array of floats containing aggregated cost score for each node in the graph ordered by node ID.

Raises:

KeyError – cost_type wasn’t set to an empty string or the key of any cost type in the graph.
