Input

Import libraries

In [ ]:

from geopy.geocoders import Nominatim
try:
    import folium
except ModuleError:
    !pip install folium --user
    import folium

Setup variables

Mandatory

address1: Address to be used to get coordinates
address2: Address to be used to get coordinates

Optional

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

In [ ]:

# Mandatory
address1 = "Bulgaria Blvd 69, 1404 Manastirski Livadi, Sofia, Bulgaria"
address2 = "1600 Amphitheatre Parkway Mountain View, CA 94043, USA"

# Optional
zoom_start = 2

Model

Get locations

In [ ]:

geolocator = Nominatim(user_agent="geoapiExercises")
location1 = geolocator.geocode(address1)
location2 = geolocator.geocode(address2)

Create map

In [ ]:

# 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], popup=folium.Popup(location1.address)).add_to(folium_map)
folium.Marker([location2.latitude, location2.longitude], popup=folium.Popup(location2.address)).add_to(folium_map)

Output

Display map
