Reverse Geocoding Overview

Introduction

Reverse geocoding turns GPS coordinates into real places. Give us a latitude and longitude, and we'll tell you the country, city, street address, or other location details.

Quick Start Guide - Get running in minutes.


How It Works

You provide coordinates, we return location details like:

  • Country and region - Know exactly where your users are
  • Cities and neighborhoods - Get local context for personalization
  • Street addresses - Turn coordinates into human-readable locations
  • Points of interest - Identify nearby landmarks and businesses

Cloud Service

Reverse geocoding runs as a Cloud Service, so there's no local setup needed. We use high-quality location data from OpenStreetMap through our Nominatim-based solution.
