Description of an approach to sifting through large amounts of phone call metadata to find leads for new surveillance target called "GEO Mining." The author gives an example of searching for heroin-production labs in Afghanistan using GEO Mining, by filtering all phone calls in Afghanistan down to calls made near known heroin-processing labs. In this case, "The top 20 handsets were then tasked for collection, and at least one has produced reportable intelligence."
