Python draws a road map on the openstreetmap map

Use python to display latitude and longitude trajectory

Hey! Long time no see, everyone. It has been more than two years since I first posted a blog. The longitude and latitude data are displayed on the map and a path is generated to facilitate the optimization and analysis of the taxiing path in the future. The language used in this article is python, and the folium package is used. The data can be found on the flightaware website. Before using this package, pip install folium is still required.

Basic usage of folium

1. folium.Map([latitude, longitude], zoom start, width, height, control_scale, no_touch)   #zoom start is the initial zoom size of the map, the larger the value, the greater the zoom level of the map, width is pixel or percentage (int or str two forms), height map height, control_scale is whether to display the scale on the map, the default is false, no_touch is whether to prohibit touching the map or dragging the map, the default is not prohibited. These functions are optional. Generally speaking, only longitude, latitude and zoom_start are required.
2. folium.Marker([latitude, longitude]).add_to(m)   #Set a glyph on the map
3. folium.PolyLine(location = [[latitude 1, longitude 1], [latitude 2, longitude 2]...], weight, color, opacity).add_to(m) # Draw a line on the map to connect the input   coordinates

Python uses folium drawing code

After installing the folium package, we can use it. The code is as follows:

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],
