cityImage.clean_duplicate_nodes#

cityImage.clean_duplicate_nodes(nodes_gdf, edges_gdf)[source]#

Removes duplicate nodes in a network based on coincident geometry, updating both nodes and edges GeoDataFrames.

Nodes with exactly matching geometries are considered duplicates and merged into a single node. All references to duplicate node IDs in the edges GeoDataFrame are updated to the retained node ID.

Parameters:

  • nodes_gdf (GeoDataFrame) – Point GeoDataFrame containing network nodes (junctions).

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

Returns:

  • nodes_gdf (GeoDataFrame) – Cleaned nodes GeoDataFrame with duplicates removed.

  • edges_gdf (GeoDataFrame) – Edges GeoDataFrame with references to duplicate node IDs updated.
