The photograph above shows the location where the following Tweet was posted:
Love hiding in the back at work because I have a 35 year old creeper. #scared #help
It’s one of the photos in a project titled Geolocation: tributes to the Data stream, by photographers Nate Larson and Marni Shindelman. Each image in the series shows the location were a particular geotagged Twitter Tweet was posted.

The saga of anti-virus pioneer John McAfee’s run from the law is a strange one, but this much is clear: McAfee wishes geotagging wasn’t a feature built into modern cameras. After a month of fleeing from Belizean law enforcement after a neighbor was found murdered, the software tycoon was finally taken into custody this week, largely due to a single photo loaded with GPS data.

Flickr introduced an innovative location-based privacy feature today called “geofences“. It’s a way of assigning default privacy settings to certain locations for geotagged photographs. For example, you can assign a geofence with a certain radius around your home, and automatically set those photos’ location data to only be visible to your friends and family. Each user can have up to 10 geofences, and existing photographs are automatically updated to new geofence privacy settings.
Last year map geek Eric Fischer created heat maps showing where Flickr photos are taken in large cities and comparing tourist vs. local hotspots. Now he’s back again with beautiful maps showing geotagged Flickr photos and Twitter Tweets, and the maps aren’t limited to cities — there’s maps for continents (see North America above) and even the whole world! The orange dots show photos, the blue ones indicate Tweets, and a white one means both were found in that location.

As photo-making devices become more and more location aware, many people unwittingly give up a lot of privacy by publishing location-tagged images online. If privacy is something you care about and you’d rather not broadcast location data along with your photography, a free Windows program called Geotag Security can help you scrub the geotag information from your pics. All you do is select a folder to scan, and the program will check the images within for location data and remove it.

The Geotaggers’ World Atlas is an interesting series of images by Eric Fischer that shows city maps overlaid with points indicating that a photograph was taken there. The location data was obtained from Flickr and Picasa, and the resulting images are heat maps of popular photography locations.
To see additional cities, head on over to Flickr to check out the Geotaggers’ World Atlas set.
