cityImage.find_gateways(nodes_gdf, edges_gdf, column)[source]#

This function identifies junctions lying on the boundary of a district, thus connected to other districts through “bridge” edges.

Parameters:

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

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

  • column (string) – The name of the column containing the district membership.

Returns:

nodes_gdf – The updated nodes GeoDataFrame with potentially disconnected districts updated to ‘999999’.

Return type:

Point GeoDataFrame
