North Korea Uncovered is a comprehensive set of mappings of North Korea. It includes in-depth coverage of thousands of buildings, monuments, missile-storage facilities, mass graves, secret labor camps, palaces, restaurants, tourist sites, and main roads of the country, and even includes the entrance to the country's subterranean nuclear test base, the Yongbyon Nuclear Scientific Research Center.
The mapping was the result of a two-year effort by doctoral student Curtis Melvin and other volunteers, who pored over hundreds of news reports, images, accounts, books, and maps in order to identify the geographic and political sites. The result has been called one of the most detailed maps of North Korea available to the public today. It is available as a small KMZ file, viewable with Google Earth. Since April 2007, the data file has been downloaded more than 270,000 times.
