Add heatmap to a layer in Folium

Question

I have this sample code:

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

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

Answer 1

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
