Geotagging

Geotagging = the ability to tag by geographic location

Examples

"A number of websites already allow users to add location information to their pictures and to search geographically, including Zooomr, a photo-sharing site; Mappr, which maps Flickr photos; and Platial, an online atlas built with user-generated pictures, video, and comments.

Flickr's geotagging feature may distinguish itself, however, in its ease of use and efficiency. To tag a picture with a location, a user simply drags the image from a panel to a location the Yahoo map. Within about a minute, internal search-engine technology at Yahoo updates the photo and tag database, allowing the picture to be searched."
