Geotagging the location of your photos can help you do all kinds of neat things on Flickr and add some great context to your image. In additon, the flickr now providing an easier way to control who has access to the location information on your photos -- in this matter, the company has announced a new feature called "Geofences", announced Denise Leung.
Geofences help you to better manage your geo privacy settings on Flickr.
Leugn in a blog post on Flickr explained that "Geofences are special locations that deserve their own geo privacy settings." For example, you might want to create a geofence around the your "home" or "school" that only allows "Friends and Family" to see the location of the photos you geotag in that area. So the next time you upload a photo with a geotag in the radius of a geofence, it will follow the default geo privacy you've designated for that hotspot. That way, you can easily make sure that only people you trust can see the location of photos taken inside your house or any other sensitive areas while still showing the world exactly where you had those amazing cheese covered duck fat fries."
