Python 使用folium绘制leaflet地图的实现方法


						leaflet为R语言提供了API很好用，这次尝试用Python使用leaflet，需要folium

安装folium





pip install folium



一个小例子





import folium

import re



input = open('C:\\Users\\Administrator\\Desktop\\a.txt','r')

text=input.read()

list = re.split('\n',text)

location = []

for element in list:

  location.append([re.split('\|',element)[3],re.split('\|',element)[4]])

oneUserMap = folium.Map(location=[40.07645623466996,116.27861671489337],zoom_start=12)

i=1

for e in location:

  folium.RegularPolygonMarker(

  [e[0],e[1]],

  popup=str(i)+":"+e[0]+e[1],

  fill_color='#769d96',

  number_of_sides=8,

  radius=10

  ).add_to(oneUserMap)

  i+=1

line_to_hanoi = folium.PolyLine(

  location

  color = black

).add_to(oneUserMap)

oneUserMap
