osmnx 应用 可视化两张图异同的点和边

python 包介绍：osmnx_UQI-LIUWJ的博客-CSDN博客

假设我们现在有这样两个graph：（需要import osmnx as ox）

point1=(31.191184,121.516295)
G1=ox.graph_from_point(point1,dist=2000)
ox.plot_graph(G1)

 

point2=(31.191469,121.48904)
G2=ox.graph_from_point(point2,dist=2000)
ox.plot_graph(G2)

 

edge_color_lst=[]
for i in G1.edges():
    if i in G2.edges:
        edge_color_lst.append('green')
    else:
        edge_color_lst.append('red')
ox.plot.plot_graph(G1,edge_color=edge_color_lst,figsize=(100,25))

nodes_color_lst=[]
for i in G1.nodes():
    if i in G2.nodes:
        nodes_color_lst.append('green')
    else:
        nodes_color_lst.append('red')
ox.plot.plot_graph(G1,node_color=nodes_color_lst)
