Python | Calculate geographic coordinates of places using google geocoding API

To calculate the geographic coordinates (latitude and longitude) of places using the Google Geocoding API in Python, you��ll first need to have an API key from Google Cloud Platform where the Geocoding API is enabled.

Here are the general steps:

  • Get an API Key from Google Cloud Platform:

    • Go to the Google Cloud Console (console.cloud.google.com).
    • Create a new project or select an existing one.
    • Navigate to "APIs & Services" > "Credentials".
    • Click on "Create credentials" and select "API key".
    • Enable the Geocoding API for your project in the "API Library" section.

  • Install the requests module in Python (if not already installed):

pip install requests
  • Use the API key to make requests to the Geocoding API:

Here��s a basic Python script to demonstrate how to do this:

import requests import json # Replace 'YOUR_API_KEY' with your actual API key API_KEY = 'YOUR_API_KEY' # Function to get geocode def get_geocode(address): url = 'https://maps.googleapis.com/maps/api/geocode/json' # Parameters in a dictionary params = { 'address': address, 'key': API_KEY } # Send the GET request response = requests.get(url, params=params) # Raise an exception if the response status is not 200 response.raise_for_status() # Parse the JSON response geocode_data = response.json() if geocode_data.get('status') == 'OK': # Extract the latitude and longitude from the response result = geocode_data['results'][0] lat = result['geometry']['location']['lat'] lng = result['geometry']['location']['lng'] return lat, lng else: # Handle the failure case (status not OK) return None, None # Example usage address = "1600 Amphitheatre Parkway, Mountain View, CA" latitude, longitude = get_geocode(address) if latitude and longitude: print(f"The geocode for '{address}' is: Latitude: {latitude}, Longitude: {longitude}") else: print("Failed to get the geocode.")

This script defines a function get_geocode that sends a request to the Google Geocoding API with an address and the API key. It then parses the response to extract the latitude and longitude.

Please note that the Google Geocoding API is a paid service, and while there is a free tier, it might have usage limits. Always secure your API keys to prevent unauthorized usage, and keep track of the API calls made to avoid unexpected charges.
