How to Plot the Google Map using folium package in Python

If you are interested to learn about the Python Gmail -API

Folium is built on the data wrangling strengths of the Python ecosystem and the mapping strengths of the Leaflet.js (JavaScript) library. Simply, manipulate your data in Python, then visualize it on a leaflet map via Folium. Folium makes it easy to visualize data that’s been manipulated in Python, on an interactive Leaflet map. This library has a number of built-in tilesets from OpenStreetMap, Mapbox etc. 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.

How do you make a map using Folium in Python?

I used Python 3.7, Folium 0.12. 1 and Pandas 1.2.
…
Something I would like to explore in the future.

1. Step 1 — Importing Pandas and Folium. …
2. Step 2 — Getting the bike station locations and saving to a Pandas data frame. …
3. Step 3 — Keeping only the columns I need. …
4. Step 4 — Creating the map. …
5. Step 5 — Adding points to the map.

How do you plot a map in Folium?

Folium gives a folium. Marker() class for plotting markers on a map. Just pass the latitude and longitude of the location, mention the popup and tooltip and add it to the map

Required Module and Libraries

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.

Basic Map

#Import library
import folium

#Uses lat then lon. & zoomlevel 4.The bigger the zoom number, the closer in you get.
mapOBJ = folium.Map(location=[17.3616, 78.4747], zoom_start = 4, tiles = 'Stamen Terrain')

# save method of Map object, will create a map

mapOBJ.save('map2.html')

Output

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.
