What Does Geotagging Mean?
Geotagging is the process of adding metadata that contains geographical information about a location to a digital map. The data usually consists of latitude and longitude coordinates, but may also include a timestamp, as well as links to additional information. Geotag metadata can be added manually or programmatically.
Techopedia Explains Geotagging
Location identification has become a fundamental feature of many social media sites and can be a useful tool when added to business applications and medicolegal applications. For example, some social networking sites and services give out the location of their users, which allows users to know exactly where their friends are as they are logged on to that website (or check in to the service). Since devices and tracking are now ubiquitous, that social media tracking becomes a more powerful and valuable tool for users.
