They say a picture is worth a thousand words – exif data tells more

The screenshots above show how I grabbed a picture off a blog and found the exif data hidden in the metadata of the picture.  Using an exif decoding website, you put in the URL of  the photo into the website. Next the website analyses the picture and provides you with the exif data.  Locate the GPS coordinates in the exif data and throw that into google maps and you get the location of where the photo was taken.

Flickr has developed GEOFENCE.  Cool little feature to turn off location leakage via the Flickr site.  You still have to know about the feature and tune it yourself.

The term “geofence” may sound complicated, but our implementation is quite simple. A geofence is a user-defined boundary around a specific area on a map. We decided to keep the creation and editing process similar to geotagging on the photo page. We understand from developing the photo page map that it is important to provide a way to search for a location as well as simply drop something in the right place on the map. The geofence is represented by a selector-circle on a modal map panel with simple edit controls on the side.
