Reverse Geocoding to City API

Introduction

Today, our smart devices can locate our geo-coordinates in real-time and with a high level of accuracy. But, these coordinates are often useless if you cannot identify the locality information such as country/state/city associated with them.

Reverse geocoding is a process that converts latitude and longitude to readable locality properties. Reverse geocoding is an essential component of the modern web, mobile and IoT. Its use cases vary across various industries and applications.  

  • Content Personalisation and Localisation
  • Geotargeting
  • Geofencing
  • Customer data validation
  • Fraud and security threat detection 

How is BigDataCloud’s Reverse Geocoding API different?

Existing reverse geocoding providers are trying to resolve to the closest street address, a household, for the given coordinates. As a result, the quality of data widely varies for mobile and regional users and exhibits slower response times.

Our Reverse Geocoding API is the first to deliver administrative/non-administrative boundaries-based results. Hence, the API is perfectly suitable for determining locality areas such as a suburb, city, state or country, rather than a street address, resulting in much faster response times and excellent support even for less populated areas. 

  • Unprecendly fast response time (sub-millisecond)
  • Delivers Administrative/non-administrative boundaries-based results
  • Provides detailed locality information of a user in 147 common world languages
  • Full postal code level accuracy for the US, Great Britain, and Australia (partial for other countries)
