Geotagging: how it works

Published 24/03/2014 | 02:30

GEOTAGGING is the process of adding geographical information to photographs, videos or other social media content.

It allows your friends to know where a particular picture was taken or from where you're posting a message.

In smartphones and tablets, data such as longitude and latitude coordinates are automatically recorded by a built-in GPS chip.

By geotagging photographs, users can search for images taken at or near a specific location.

It has experienced a surge in popularity in recent years, as smartphones with built-in GPS functionality have become the norm.

Geotags can be read by any device which reads geotagging metadata, such as image editors and online image galleries. However, the geotagging facility can be turned off so your exact location isn't added to your photos or messages.
