Crandall et al (2009) investigate how to trace photographic images collected through Flickr, with combination of text tags, images with geospatial data, and estimating locations based on geographical features.
Elizabeth Currid and Sarah Williams analysed thousands of Getty Images photographs, beginning in March 2006, to "to quantify and understand, visually and spatially, how this creative cultural scene really worked” (Currid, in Ryzik, 2009).
"We're going to see more research that’s using these types of finer-grained data sets, what I call data shadows, the traces that we leave behind as we go through the city," she [Williams] said. "They’re going to be important in uncovering what makes cities so dynamic." (Ryzik, 2009)Mapping the World's Photos [PDF]
