Introduction

Our task was to optimize the management of a care provider company and enhance their services using location-based search. The problem we faced was that caregivers needed to manually search through their database to determine where caretakers lived and which caregivers lived nearby to connect them efficiently. 

This led us to explore how Google Maps API could revolutionize the way we handle address-based searches and distance calculations in our application.

By integrating this powerful geolocation service, we’ve made the lives of dispatchers much easier by streamlining their workflow. Now, they no longer need to sift through large databases and filter by postcodes or regions. Instead, they can simply search by distance using the target location.

Why Google Maps API is a Good Option for Geolocation Services

Google Maps API is a versatile and widely-used solution that offers accurate and reliable geospatial data. With its comprehensive coverage, fast response times, and easy integration, it’s an ideal choice for developers looking to enhance their applications with geolocation capabilities. Furthermore, Google Maps API provides extensive documentation and support, making it accessible for developers with varying levels of experience.

Step-by-step guide on how to integrate Google Maps API into your application for address-based search and distance calculation

1. Sign up for Google Cloud Console: To access the APIs, create a new project and configure your billing account. Don’t worry, Google offers free quotas initially.

2. Enable the required API service: Choose from hundreds of available APIs and create credentials for your application. For our project, we used the Geocoding API to convert addresses into coordinates.

3. Integrate a client library: Google provides easy-to-use libraries for various programming languages, simplifying the implementation process. Visit https://developers.google.com/maps/web-services/client-library  for more information.

4. Make API calls: In our case, we limited the search results to Slovenia, as our dispatching system currently operates exclusively within the country. This helps avoid unexpected results.

5. Implement the API into your distance search functionality:

  • Pre-calculate coordinates for existing database entries.
  • Upon search, retrieve the coordinates of a search query, order the database entries by distance, and display the closest first.

6. Create an easy-to-use view: Allowing dispatchers to search by location within the CRM:

Google API Pricing and cost management

The Geocoding API, which we used for our project, costs €0.005 per call. Google Maps API operates on a pay-as-you-go model, and while the initial quotas are free, the costs can accumulate quickly, especially for applications with a high volume of requests.

Tips for managing expenses: 

  • Monitor usage: Regularly check your Google Cloud Console and set up custom dashboards to track API usage and stay within budget.
  • Set up alerts: Configure budget alerts to receive notifications when spending exceeds specified thresholds.
  • Optimize requests: Minimize API calls by caching and reusing previous request results when appropriate.
  • Review pricing tiers: Evaluate different tiers based on usage volume and determine if you qualify for discounted rates.
