获取航线信息并且制作成图
航线信息
航线信息查询网站
本次实例使用的航班号为 CES5496
查询后在network中可以寻找到如下内容https://zh.flightaware.com/ajax/ignoreall/trackpoll.rvt?token=c35ca45ecbca57cd1ea443d1c65c36426ea06630de026ffde4a40a26ead614b3f2dddec214a859f7965-dd46e66d5342d62a1946f71668e4cef966e8f-570f2ace7c0aecf8e28ced6893a0e805cc9ef5bd&locale=zh_CN&summary=1
上述url即为本次航班号查询的结果，在[‘flights’][‘CES5496–airline-0406:0’][‘track’] 下存放了本次航班的坐标数据
写入本地文件
import requests
import json
url = “https://zh.flightaware.com/ajax/ignoreall/trackpoll.rvt?token=c35ca45ecbca57cd1ea443d1c65c36426ea06630de026ffde4a40a26ead614b3f2dddec214a859f7965-dd46e66d5342d62a1946f71668e4cef966e8f-570f2ace7c0aecf8e28ced6893a0e805cc9ef5bd&locale=zh_CN&summary=1”
html = requests.get(url)
with open(‘CES5496.json’,’w’) as f:
json.dump(html.text,f)
解析json文件
把json文件中的相关坐标信息 提取到一个list中以便使用
import json
with open(‘CES5496.json’, encoding=’utf-8′) as data_file:
data = json.loads(data_file.read().replace(‘true’,’True’).replace(‘null’,’None’).replace(‘false’,’False’))
jdata = dict(eval(data))
xy = jdata[‘flights’][‘CES5496–airline-0406:0’][‘track’]coordList = list()
for index in range(xy.__len__()):
# print(xy[index])
coordList.append(xy[index][‘coord’][::-1])
print(coordList)
绘制图形
使用的库为folium
使用folium.PolyLine 绘制线
使用plugins.PolyLineTextPath 绘制飞机
from folium import plugins
import folium
m = folium.Map([30.1833, 120.2833], zoom_start=5)
