Photo-sharing website flickr recently reached a milestone. Over the weekend, the amount of the site's photos that has been geotagged passed the 100,000,000 mark. This is an opportunity to discuss geotagging.
Geotagging is a feature that flickr developed almost three years ago. Like flickr's text tags, geotags aid other users in finding photos of a specific kind; geotags allow users to find photos taken at a particular place. Unlike conventional tags, however, geotags are not text-based. Instead, users can use a map app similar to Google Maps to pinpoint exactly where one of their uploaded photos was taken. The popularity of geotagging (as the post indicates, almost 3.5% of flickr's three billion photos have been geotagged) actually affected the digital camera industry. Nikon recently released a camera attachment that automatically inserts geotag data into a photograph's metadata (like EXIF and IPTC).
