突出显示Folium中的一个特定国家 [英] Highlight one specific country in Folium

问题描述

我有一张由大叶草绘制的地图，如下所示：

  m = folium.Map（location = [51.1657,10.4515] ，zoom_start = 6，min_zoom = 5，max_zoom = 7）
  

我如何摆脱邻国而只保留德国？
或者邻近的国家变得褪色，模糊，苍白或类似的东西。

解决方案

包含感兴趣国家/地区的几何图形（坐标）的json文件，您可以添加

I have a map drawn by folium as follow:

m = folium.Map(location = [51.1657,10.4515], zoom_start=6, min_zoom = 5, max_zoom = 7)

How can I get rid of neighbor countries and just keep Germany? Or alternatively neighbor countries become fade, blur,pale or something like this.

解决方案

As long as you have a json file containing the geometry (coordinates) for the country of interest, you can add a GeoJson layer:

import folium
import json

with open('datasets/world-countries.json') as handle:
    country_geo = json.loads(handle.read())

for i in country_geo['features']:
    if i['properties']['name'] == 'Germany':
        country = i
        break

m = folium.Map(location = [51.1657,10.4515],
               zoom_start=6,
               min_zoom = 5,
               max_zoom = 7)


folium.GeoJson(country,
               name='germany').add_to(m)

folium.LayerControl().add_to(m)

m

and you get:
