Description: This notebook demonstrates how to add markers on a map using folium.

• Folium Mapping: Displaying Markers on a Map

Input

Import libraries

try:
    import folium
except ModuleError:
    !pip install folium --user
    import folium

Setup variables

Mandatory

• location1_coordinates: Coordinates to be used for location: latitude, longitude

• location2_coordinates: Coordinates to be used for location: latitude, longitude

Optional

• zoom_start: This parameter sets the initial zoom level on the map. A value of 0 indicates the lowest level of zoom.

# Mandatory
location1_coordinates = 42.657188, 23.2846605
location2_coordinates = 37.4217636, -122.084614

# Optional
zoom_start = 2

Model

Get coordinates

# location 1
location1_latitude = location1_coordinates[0]
location1_longitude = location1_coordinates[1]

# location 2
location2_latitude = location2_coordinates[0]
location2_longitude = location2_coordinates[1]

Create map

# Create a map centered around the two locations
avg_latitude = (location1_latitude + location2_latitude) / 2
avg_longitude = (location1_longitude + location2_longitude) / 2
folium_map = folium.Map(location=[avg_latitude, avg_longitude], zoom_start=zoom_start)

# Add markers for the specified locations
folium.Marker([location1_latitude, location1_longitude]).add_to(folium_map)
folium.Marker([location2_latitude, location2_longitude]).add_to(folium_map)

Output

Display map
