For all the saber-rattling North Korea has been doing, precious little is known about daily life in the isolated nation. Even a railway map is close to classified information.
A doctoral student at George Mason University is using satellite images to get a closer look at a historically secretive country. North Korea is once again in the news because of its growing nuclear threat and the imprisoning of two American journalists. By closely examining Google Earth and corroborating physical evidence of infrastructure with reports from visitors and defectors, Curtis Melvin has assembled a workable map of North Korean railways — not to mention hidden palaces and outdoor food markets. The Google Earth overlays are available at his blog, North Korean Economy Watch.
