cityImage.graph_fromGDF#

cityImage.graph_fromGDF(nodes_gdf, edges_gdf, nodeID='nodeID')[source]#

From two GeoDataFrames (nodes and edges), it creates a NetworkX undirected Graph.

Parameters:

  • nodes_gdf (Point GeoDataFrame) – The nodes (junctions) GeoDataFrame.

  • edges_gdf (LineString GeoDataFrame) – The street segments GeoDataFrame.

  • nodeID (str) – Column name that indicates the node identifier column (if different from “nodeID”).

Returns:

G – The undirected street network graph.

Return type:

NetworkX.Graph
