在OSMnx地图顶部绘制多段线

import osmnx as ox
import networkx as nx
import matplotlib.pyplot as plt

place_name = "地点名称"  # 可以是城市名称、地址等
graph = ox.graph_from_place(place_name, network_type="all")

fig, ax = ox.plot_graph(ox.project_graph(graph))

start_point = (latitude1, longitude1)
end_point = (latitude2, longitude2)

start_node = ox.distance.nearest_nodes(graph, start_point[0], start_point[1])
end_node = ox.distance.nearest_nodes(graph, end_point[0], end_point[1])
route = nx.shortest_path(graph, start_node, end_node, weight="length")

route_map = ox.plot_graph_route(graph, route, route_linewidth=6, node_size=0, bgcolor='k', edge_color='r', show=False, close=False)

fig, ax = plt.subplots()
ax.imshow(route_map)
