This is a nice feature from Flickr. Flickr is introducing Geofences for your pictures. It is a new feature aimed at helping users better manage the privacy settings around their geotagged photos.
With Geofences, you can limit who is able to see the location data associated with images taken from within a specified area. You can create parameters around specific geographic areas by drawing a circle on a map and choosing a geo-privacy setting for that area. Users can add up to 10 geofences and set a parameter approximately 7-10 km wide.
