How to Plot the Google Map using folium package in Python

The folium package is built on the data wrangling strengths of the Python ecosystem and the mapping strengths of the Leaflet.js library of JavaScript language. The user can manipulate their data by using Python and then visualize it by using Leaflet.js map through folium package. Folium package is an easy approach of visualizing the data on Leaflet.js map, which has been manipulated by using Python.

Required Module and Libraries

If we want to plot the Google Map using python, we have to install folium or geopy module in it.

Folium:

The user can install the Folium package by using the following command.

pip install folium  

Geopy:

The geopy module of Python makes it easy for Python users to locate the coordinates of landmarks, cities, countries on the earth’s surface. For installing the geopy module, the user can use the following command:

pip install geopy  

After successful installation of the both libraries, we follow the below steps to plot Google map.

Step for Plotting the Google Map using Folium package

Following steps are used to plot the Google Map using Folium package in Python:

Step 1: Create the Base map

The user can create the base map by using the following program:

import os  

# First, import folium package  

import folium  

from geopy.geocoders import Nominatim as NT  

# Initialize Nominatim API  

geo_locator = NT(user_agent = "geoapiExercises")  

# write the place  

place_1 = "Yemen"  

  

location_1 = geo_locator.geocode(place_1)  

# now, it will search for the location by using the latitude and longitude, with zoom_start = 15  

user_map1 = folium.Map(location = [location_1.longitude, location_1.latitude],  

                                        zoom_start = 15 )  

# At last, open the base map  

user_map1

Output:

Step 2: Add a Circular Marker

The user can mark the area with the circle and popup text by using the following code:

import folium  

   

from geopy.geocoders import Nominatim as NT  

  

geo_locator = NT(user_agent = "geoapiExercises")  

  

place_1 = "Yemen"  

  

location_1 = geo_locator.geocode(place_1)  

  

user_map1 = folium.Map(location = [location_1.longitude, location_1.latitude],  

                                        zoom_start = 15 )  

   

# CircleMarker with radius  

folium.CircleMarker(location = [location_1.longitude, location_1.latitude],  

                    radius = 45, popup = ' YEMEN ').add_to(user_map1)  

   

# Now, open the Map with circular Mark  

user_map1

Output:

Step 3: Add the simple marker for the parachute style marker with the popup text

The user can use the following code.

Example:

import os  

import folium  

   

from geopy.geocoders import Nominatim as NT  

  

geo_locator = NT(user_agent = "geoapiExercises")  

  

place_1 = "Yemen"  

  

location_1 = geo_locator.geocode(place_1)  

  

user_map1 = folium.Map(location = [location_1.longitude, location_1.latitude],  

                                        zoom_start = 15)  

#Now, we will pass the string in popup parameter  

folium.Marker([location_1.longitude, location_1.latitude],  

               popup = ['YEMEN']).add_to(user_map1)  

# now, open the map   

user_map1

Output:

Step 4: Add the line on the map

The user can use the following code for adding the line on the map to join the two coordinates.

Example:

# First, import folium package  

import folium  

import os   

from geopy.geocoders import Nominatim as NT  

  

geo_locator = NT(user_agent = "geoapiExercises")  

  

place_1 = "Aden"  

place_2 = "Yemen"  

location_1 = geo_locator.geocode(place_1)  

location_2 = geo_locator.geocode(place_2)  

user_map1 = folium.Map(location = [location_1.longitude, location_1.latitude],  

                                        zoom_start = 6)  

   

folium.Marker([location_1.longitude, location_1.latitude],  

               popup = ['Aden']).add_to(user_map1)  

   

folium.Marker([location_2.longitude, location_2.latitude],  

              popup = 'Yemen').add_to(user_map1)  

   

# Now, we will add the line on the map by using Polyline method .  

# it will connect both coordinates by the line  

   

folium.PolyLine(locations = [[location_1.longitude, location_1.latitude], [location_2.longitude, location_2.latitude]],  

                line_opacity = 0.5).add_to(user_map1)  

# now, open the map  

user_map1

Output:

Explanation

We used the geopy library to get the latitude and longitude of the location. Then we used the “folium.map” method of the folium package for creating the base of Google Maps.

In step 2, we used “folium.CircleMarker” for marking the circular mark on the location with the pop-up text. In step 3, we used “folium.Marker” to add a parachute style mark on the mentioned location. In the last step, we used “folium.PolyLine” for joining two marks on two different locations on the map.

Conclusion

In this tutorial, we have shown how the user can Plot the Google map and add different required functionalities on the map like a circular mark, parachute mark, pop-up text, and the line joining the two coordinates on the map.
