从 OSMNX 中的不同地址下载街道

Question

我想使用列表在 osmnx 中下载不同的街道，但我在我的代码中找不到错误。

我试过这种方法

name_list = ['Kuwait, United Arab Emirates','Guangzhou, China']

i=0
for file_path in name_list:
    print(i)
    CD = file_path
    filtro_vialidades = '["highway"~"trunk|motorwat|primary|secondary|tertiary|residential"]'
    GCD=ox.graph_from_address(CD, network_type= "drive",
                              custom_filter= filtro_vialidades)
    ox.save_graphml(GCD, f"{name_list[i]}.graphml", gephi= False)
    i+=1  

#I had this error

EmptyOverpassResponse: There are no data elements in the response JSON

Answer 1

它似乎无法为您的某个查询找到任何内容，可能是因为“阿拉伯联合酋长国科威特”不存在。这是两个不同的国家。

Answer 2

科威特是一个国家而不是一个城市。您可以添加适当的错误处理代码：

import osmnx as ox
from osmnx._errors import EmptyOverpassResponse

name_list = ['Kuwait, United Arab Emirates','Guangzhou, China']

for i, file_path in enumerate(name_list):
    print(i)
    CD = file_path
    filtro_vialidades = '["highway"~"trunk|motorwat|primary|secondary|tertiary|residential"]'
    try:
        GCD=ox.graph_from_address(CD, network_type= "drive",
                                  custom_filter= filtro_vialidades)
        ox.save_graphml(GCD, f"{name_list[i]}.graphml", gephi= False)
    except EmptyOverpassResponse:
        print(f"no results: {file_path}")
