Get Longitude and Latitude from Address using Google Maps API
This video demonstrates how to use the Get Longitude and Latitude from Address using Google Maps API template.
import os
import requests
from fastapi import FastAPI, Form, HTTPException
from pydantic import BaseModel
app = FastAPI()
# The builder needs to provide the Google Maps API key via the Env Secrets tab.
# The environment variable name should be GOOGLE_MAPS_API_KEY.
@app.post("/get_address_coordinates", summary="Get Address Coordinates", description="Fetches latitude and longitude based on address using Google Maps API.")
async def get_address_coordinates(address: str = Form(...)):
google_maps_api_key = os.environ.get('GOOGLE_MAPS_API_KEY')
if not google_maps_api_key:
raise HTTPException(status_code=500, detail="Google Maps API key is not set.")
try:
# The Google Maps Geocoding API endpoint
url = f"https://maps.googleapis.com/maps/api/geocode/json?address={address}&key={google_maps_api_key}"
response = requests.get(url)
response.raise_for_status()
geocode_data = response.json()
if geocode_data['status'] == 'OK':
# Extracting latitude and longitude from the first result
latitude = geocode_data['results'][0]['geometry']['location']['lat']Frequently Asked Questions
What are some business applications for this Address to Coordinates converter?
The Get Longitude and Latitude from Address using Google Maps API template has numerous business applications: - Real estate: Plotting property locations on interactive maps - Logistics: Optimizing delivery routes and tracking shipments - Retail: Analyzing store locations and planning new expansions - Marketing: Geo-targeting campaigns and analyzing customer demographics - Tourism: Creating location-based travel guides and itineraries
How can this template improve customer experience in a business setting?
The Address to Coordinates converter can enhance customer experience by: - Providing accurate location-based services - Enabling precise navigation to business locations - Facilitating location-aware features in mobile apps - Improving the accuracy of local search results - Enhancing visualization of data on maps for better decision-making
What industries could benefit most from implementing this Google Maps API integration?
Several industries can greatly benefit from the Get Longitude and Latitude from Address using Google Maps API template: - E-commerce and delivery services - Real estate and property management - Travel and hospitality - Urban planning and smart city initiatives - Insurance (for risk assessment based on location) - Telecommunications (for network planning)
How can I modify the template to return additional location data?
You can modify the get_address_coordinates function to return more information from the Google Maps API response. For example, to include the formatted address:
python
@app.post("/get_address_coordinates")
async def get_address_coordinates(address: str = Form(...)):
# ... existing code ...
if geocode_data['status'] == 'OK':
result = geocode_data['results'][0]
return {
"latitude": result['geometry']['location']['lat'],
"longitude": result['geometry']['location']['lng'],
"formatted_address": result['formatted_address']
}
This modification will return the formatted address along with the coordinates.
Can I use this template with a different geocoding service instead of Google Maps?
Yes, you can adapt the Get Longitude and Latitude from Address using Google Maps API template to work with other geocoding services. You'll need to modify the API endpoint and possibly the response parsing. Here's an example using the OpenStreetMap Nominatim API:
python
@app.post("/get_address_coordinates")
async def get_address_coordinates(address: str = Form(...)):
try:
url = f"https://nominatim.openstreetmap.org/search?q={address}&format=json"
headers = {'User-Agent': 'YourAppName'}
response = requests.get(url, headers=headers)
response.raise_for_status()
data = response.json()
if data:
return {"latitude": float(data[0]['lat']), "longitude": float(data[0]['lon'])}
else:
raise HTTPException(status_code=404, detail="Address not found.")
except requests.RequestException as e:
raise HTTPException(status_code=400, detail=str(e))
Note that when using OpenStreetMap's Nominatim, you should follow their usage policy, which includes setting a proper User-Agent header.

Introduction to the Template
Welcome to the "Get Longitude and Latitude from Address using Google Maps API" template. This template is designed to help you quickly set up a FastAPI web server that provides an endpoint to fetch geographical coordinates based on a given address. It's a straightforward and efficient way to integrate location-based services into your applications.
Clicking Start with this Template
To begin using this template, simply click on the "Start with this Template" button. This will initialize the template in the Lazy Builder interface, pre-populating the code for you.
Initial Setup
Before you can use the template, you need to set up an environment secret for the Google Maps API key. Here's how to acquire and set up your API key:
- Visit the Google Cloud Platform Console.
- Create a new project or select an existing one.
- Go to the "APIs \& Services" dashboard, and enable the Geocoding API for your project.
- Go to the "Credentials" page and click on "Create credentials" to generate a new API key.
- Copy the generated API key.
- In the Lazy Builder interface, navigate to the Environment Secrets tab.
- Create a new secret with the name
GOOGLE_MAPS_API_KEYand paste your copied API key as the value.
Test: Pressing the Test Button
Once you have set up your Google Maps API key in the Environment Secrets, you can test the application by pressing the "Test" button. This will deploy your app and launch the Lazy CLI.
Entering Input
After pressing the "Test" button, the Lazy App's CLI interface will appear. You will be prompted to provide the address for which you want to fetch the coordinates. Enter the address as instructed by the CLI.
Using the App
After entering the address, the application will process your request and return the latitude and longitude of the specified address. You will receive a server link through the Lazy builder CLI to interact with the API. Additionally, since this template uses FastAPI, you will also be provided with a link to the API documentation, which can be used to explore other available endpoints and their usage.
Integrating the App
If you wish to integrate this API into an external service or frontend, you can use the server link provided by Lazy. Here's a sample request you might make to the API:
`POST /get_address_coordinates
Content-Type: application/x-www-form-urlencoded
address=1600+Amphitheatre+Parkway,+Mountain+View,+CA` And here's a sample response you might receive:
{
"latitude": 37.4224764,
"longitude": -122.0842499
}
Use the provided server link to send requests from your external service or frontend to fetch coordinates for different addresses. Ensure that you handle user input securely and validate it before sending it to the API.
By following these steps, you can seamlessly integrate the "Get Longitude and Latitude from Address using Google Maps API" template into your application, providing valuable location-based functionalities to your users.
