将热图添加到Folium中的图层 [英] Add heatmap to a layer in Folium

问题描述

我有此示例代码：

from glob import glob
import numpy as np
import folium
from folium import plugins
from folium.plugins import HeatMap

lon, lat = -86.276, 30.935 
zoom_start = 5


data = (
    np.random.normal(size=(100, 3)) *
    np.array([[1, 1, 1]]) +
    np.array([[48, 5, 1]])
).tolist()
m = folium.Map([48, 5], tiles='stamentoner', zoom_start=6)

HeatMap(data).add_to(m)
m

如何将热图添加到图层中，以便在需要时将其隐藏？

How can I add this heat map to a layer so I can hide it if needed?

推荐答案

我首先将HeatMap添加到FeatureGroup，然后将该FeatureGroup添加到map（m）。然后，我将LayerControl添加到您的地图（检查右上角）。足够了吗？

I would first add your HeatMap to a FeatureGroup and then add that FeatureGroup to the map(m). I would then add a LayerControl to your map (check the upper right corner). Does this suffice?

from glob import glob
import numpy as np
import folium
from folium import plugins
from folium.plugins import HeatMap

lon, lat = -86.276, 30.935 
zoom_start = 5


data = (
    np.random.normal(size=(100, 3)) *
    np.array([[1, 1, 1]]) +
    np.array([[48, 5, 1]])
).tolist()
m = folium.Map([48, 5], tiles='stamentoner', zoom_start=6)

HeatMap(data).add_to(folium.FeatureGroup(name='Heat Map').add_to(m))
folium.LayerControl().add_to(m)

m
