The Soviet Military Program that Secretly Mapped the Entire World

Greg Miller at National Geographic:

During the Cold War, the Soviet military undertook a secret mapping program that’s only recently come to light in the West. Military cartographers created hundreds of thousands of maps and filled them with detailed notes on the terrain and infrastructure of every place on Earth. It was one of the greatest mapping endeavors the world has ever seen.

Fascinating.
