效果如下：

一、folium安装

我是直接使用anaconda prompt安装：pip install folium

二、绘制路径

folium的坐标系是WGS84坐标系。

import folium
import os
import pandas as pd
import numpy as np


def read_gps_data(path):
    P = pd.read_csv(path, header=None, dtype=np.double).values  # 读取csv文件，输出为narray
    locations_nav = P[:, 0:2].tolist()  # narray转换成list
    locations_true = P[:, 2:4].tolist()
    return locations_nav, locations_true


def draw_gps(locations_nav, locations_tr
