Geolocation API

The Geolocation API allows web applications to access a device's physical coordinates via GPS, Wi-Fi, or IP address tracking.

This interface provides high-level access to location data (latitude, longitude, and altitude) through the navigator.geolocation object. It supports one-time position requests using getCurrentPosition() and continuous tracking via watchPosition() for real-time navigation. Modern browsers secure this data behind strict user-permission prompts and require HTTPS to protect sensitive telemetry. Developers use it to power local search results, geofencing triggers, and interactive mapping tools across mobile and desktop environments.
