嘿！各位好久不見，距離第一次發(fā)博客已經(jīng)過去兩年多了，本人也從本科生變成了研究生，好了書歸正傳，最近在做一個(gè)關(guān)于航班滑行路徑軌跡的項(xiàng)目，目的是將航班的經(jīng)緯度數(shù)據(jù)在地圖上顯現(xiàn)出來并生成一條路徑，以方便日后的滑行路徑優(yōu)化與分析。本文所用的語言為python，使用的是folium包，數(shù)據(jù)在flightaware網(wǎng)站上可以找到，使用這個(gè)包之前還是需要先進(jìn)行pip install folium

folium的基本用法

• folium.Map([緯度，經(jīng)度]，zoom start，width，height，control_scale，no_touch)   #zoom start為地圖的初始縮放尺寸，數(shù)值越大地圖放大程度就會(huì)越大，width為像素或百分比(int或者str兩種形式)，height地圖高度，control_scale為是否需要在地圖上顯示比例尺，默認(rèn)為false，no_touch為是否禁止觸碰地圖或拖拽地圖，默認(rèn)為不禁止。這些功能都是可自己選擇的，一般來說只需要經(jīng)度緯度和zoom_start就好了
  
• folium.Marker([緯度，經(jīng)度]).add_to(m)   #在地圖上設(shè)置一個(gè)標(biāo)志符號(hào)
  
• folium.PolyLine(location = [[緯度1，經(jīng)度1],[緯度2，經(jīng)度2]...]，weight，color，opacity).add_to(m)   #在地圖上劃線將所輸入坐標(biāo)連接起來
  

python利用folium繪圖代碼

在裝好folium包以后呢，我們就可以使用起來啦，代碼如下所示：

from folium import plugins
import folium
import os
m = folium.Map([39.1289, 117.3539], zoom_start=10) #中心區(qū)域的確定
