Perl, Ghostscript, Flickr API, and Picasa API software
Locals and Tourists uses geotagging data from the photo-sharing websites Flickr and Picasa to visualize the different areas frequented by locals and tourists in New York, London, and 124 other cities, including Taipei, Sydney, Berlin, and San Jose, California. After harvesting millions of data points in the form of photographs, Eric Fischer links them by photographer and date and then plots them on a city’s OpenStreetMap grid. A photographer with many shots of the same city and a long photo history can be assumed to be a local and is represented in blue, and someone whose photos are taken within a limited time period is assumed to be a tourist and represented in red; photographers whose status can’t be determined are represented in yellow.
