Have you ever used geo-tagging? If yes, please explain what did you do? If no, please explain the definition of geo-tagging.
Geo-tagging (also known as geo-location) is attaching location based data automatically with every picture taken by most smartphone cameras. Location information is typically given in terms of latitude and longitude coordinates, which can pinpoint the place where photo was taken. Geo-tagging could be used through the “check in” feature of Facebook.
