"I Know Where Your Cat Lives visualizes public photos of cats on a world
map using coordinates embedded in their metadata.
"I Know Where Your Cat Lives" iknowwhereyourcatlives.com is a data
experiment that visualizes a sample of 1 million public pics of cats on
a world map, locating them by the latitude and longitude coordinates
embedded in their metadata. The cats were accessed via publicly
available APIs provided by popular photo sharing websites. The photos
were then run through various clustering algorithms using a
supercomputer at Florida State University in order to represent the
enormity of the data source.
