Perhaps more so than any other tool used by the clandestine services, an accurate map can mean the difference between success and failure, or life and death.

The CIA, renowned for its secrecy, has long kept its maps and cartographic methods under wraps.

But, in honor of the agency’s Cartography Center’s 75th anniversary, the CIA put a number of maps online, depicting how “the company” has viewed the world since its inception in the aftermath of World War II.

President Franklin Roosevelt created the agency that would eventually become the CIA in the early 1940s. The map division produced a bevy of maps vital to strategic planning during the war, according to National Geographic.

The agency’s mapmakers had a broad mission, asked to produce maps and data relevant to whatever national security issues the country may have encountered. In the process, “Geographers and cartographers amassed what would be the largest collection of maps in the world.”

In a sign of how valuable maps were during the Cold War, the Soviet Union dedicated a great deal of resources and time to not only making exacting maps of foreign capitals and other cities, but also to make misleading maps of their own territory, meant to disrupt the movements of anyone who acquired those maps with nefarious intent.
