Question

我有一个带lat / lon坐标的数据框

latlon
(51.249443914705175, -0.13878830247011467)
(51.249443914705175, -0.13878830247011467)
(51.249768239976866, -2.8610415615063034)
...

我想将这些绘制到Folium地图上，但我不确定如何遍历每一行。

任何帮助将不胜感激，提前致谢！

Answer 1

以下是我的做法，我实际上是在尝试整理一个例子的笔记本（添加颜色，弹出窗口等）。我还在解决这些问题，但你可以在这里找到它：

https://github.com/collinreinking/longitude_latitude_dot_plots_in_python_with_folium

import folium
import pandas as pd

#create a map
this_map = folium.Map(prefer_canvas=True)

def plotDot(point):
    '''input: series that contains a numeric named latitude and a numeric named longitude
    this function creates a CircleMarker and adds it to your this_map'''
    folium.CircleMarker(location=[point.latitude, point.longitude],
                        radius=2,
                        weight=0).add_to(this_map)

#use df.apply(,axis=1) to "iterate" through every row in your dataframe
data.apply(plotDot, axis = 1)


#Set the zoom to the maximum possible
this_map.fit_bounds(this_map.get_bounds())

#Save the map to an HTML file
this_map.save('html_map_output/simple_dot_plot.html')

this_map

这可以解决您的问题

import folium
mapit = None
latlon = [ (51.249443914705175, -0.13878830247011467), (51.249443914705175, -0.13878830247011467), (51.249768239976866, -2.8610415615063034)]
for coord in latlon:
    mapit = folium.Map( location=[ coord[0], coord[1] ] )

mapit.save( 'map.html')

mapit = folium.Map( location=[52.667989, -1.464582], zoom_start=6 )
for coord in latlon:
    folium.Marker( location=[ coord[0], coord[1] ], fill_color='#43d9de', radius=8 ).add_to( mapit )

mapit.save( 'map.html')
