Uncomment the following line to install leafmap if needed.

In [1]:

# !pip install leafmap

# !pip install leafmap

Specify the file path to the CSV. It can either be a file locally or on the Internet.

In [2]:

filepath = "https://raw.githubusercontent.com/opengeos/leafmap/master/examples/data/us_cities.csv"

filepath = "https://raw.githubusercontent.com/opengeos/leafmap/master/examples/data/us_cities.csv"

Use the ipyleaflet plotting backend.

In [3]:

import leafmap.leafmap as leafmap

import leafmap.leafmap as leafmap

Specify the latitude, longitude, and value columns to create the heat map.

In [4]:

m = leafmap.Map()
m.add_heatmap(
    filepath,
    latitude="latitude",
    longitude="longitude",
    value="pop_max",
    name="Heat map",
    radius=20,
)
m

m = leafmap.Map() m.add_heatmap( filepath, latitude="latitude", longitude="longitude", value="pop_max", name="Heat map", radius=20, ) m

Use the folium plotting backend.

In [5]:

import leafmap.foliumap as leafmap

import leafmap.foliumap as leafmap

Specify the latitude, longitude, and value columns to create the heat map.

In [6]:

m = leafmap.Map()
m.add_heatmap(
    filepath,
    latitude="latitude",
    longitude="longitude",
    value="pop_max",
    name="Heat map",
    radius=20,
)
m

m = leafmap.Map() m.add_heatmap( filepath, latitude="latitude", longitude="longitude", value="pop_max", name="Heat map", radius=20, ) m
