The MIT SESEABLEcity lab produced a clip of a visualization of geotagged Flickr photographs located in Spain. The visualization covers a time period of one year and gives a good impression of which spots get photographed by digital and web enthusiasts.
“(Un)photographed Spain maps thousands of these public, digital footprints over one year. As photos overlap in certain locations, they expose the places that attract the photographer's gaze . In contrast, the absence of images in other locations reveal the unphotographed spaces of a more introverted Spain.” (by senseablecity on vimeo)
