I have been attempting to determine if this geofence feature now available in Flickr is useful. The concept is that you can define an area and if images in your account are geotagged within that area you can limit who can view.
We actually have a camera that geotags photos but very view people do. The most likely issue would involve the use of a cell phone that tags images. If you manually geotag images, I would think you could also set access privileges.
I guess if I were a teacher and used a cell phone that tagged images with location from my school and I was concerned that some might object to me including these images so that anyone could see and know the location of the school, this might be a useful safeguard.
That is a lot of “ands” –
I seem to remember that getting Flickr to recognize the geotags in the images I uploaded was a hassle and required that had to I change a setting. Maybe this has changed – at that time (see this description) the problem was how to get Flickr to recognize the location data in the exif.
Now the assumptions seem to be that many people want to include geotags, but have the problem of getting the system to ignore geotags that might reveal personal location.
