python - Finding the exact name of City and Country

Question

import osmnx as ox
%matplotlib inline
G = ox.graph_from_place('Seoul, South Korea', network_type='drive')
fig, ax = ox.plot_graph(ox.project_graph(G))

In this part, how to find the exact title of city and country? It does not work for Seoul, South Korea.

I have tried a few times but it was failed.

import osmnx as ox
%matplotlib inline
G = ox.graph_from_place('Seoul, South Korea', network_type='drive')
fig, ax = ox.plot_graph(ox.project_graph(G))

Answer 1

不是名称问题的正确解决方案，但有用的解决方法是使用 lat/lon 坐标作为参数ox.graph_from_point()：

G = ox.graph_from_point([37.5666791, 126.9782914],
                        distance=30000,
                        network_type='drive')

你得到：

这似乎是首尔的一个具体问题，因为我在其他城市和地区尝试过它并且它奏效了。在这种情况下，您可以尝试结合城市内部区域的图表或作为句子回答使用坐标甚至 bbox。
