python在openstreetmap地图上绘制路线图的实现

利用python进行经纬度轨迹展示

嘿！各位好久不见，距离第一次发博客已经过去两年多了，本人也从本科生变成了研究生，好了书归正传，最近在做一个关于航班滑行路径轨迹的项目，目的是将航班的经纬度数据在地图上显现出来并生成一条路径，以方便日后的滑行路径优化与分析。本文所用的语言为python，使用的是folium包，数据在flightaware网站上可以找到，使用这个包之前还是需要先进行pip install folium

folium的基本用法

• folium.Map([纬度，经度]，zoom start，width，height，control_scale，no_touch)   #zoom start为地图的初始缩放尺寸，数值越大地图放大程度就会越大，width为像素或百分比(int或者str两种形式)，height地图高度，control_scale为是否需要在地图上显示比例尺，默认为false，no_touch为是否禁止触碰地图或拖拽地图，默认为不禁止。这些功能都是可自己选择的，一般来说只需要经度纬度和zoom_start就好了
  
• folium.Marker([纬度，经度]).add_to(m)   #在地图上设置一个标志符号
  
• folium.PolyLine(location = [[纬度1，经度1],[纬度2，经度2]...]，weight，color，opacity).add_to(m)   #在地图上划线将所输入坐标连接起来
  

python利用folium绘图代码

在装好folium包以后呢，我们就可以使用起来啦，代码如下所示：

from folium import plugins
import folium
import os
m = folium.Map([39.1289, 117.3539], zoom_start=10) #中心区域的确定
location =[[39.1289, 117.3539], [39.1277262, 117.3542938], [39.1277275, 117.3543001], [39.1277262, 117.3542938],

成果展示（这个应该是要在联网的情况下进行的，有时候图像加载的有一些慢）
