“CIA realized that quite early and launched its Cartography Center back in October 1941. Since the beginning the mission of the unit was to provide a full range of maps, geographic analysis, and research in support of the Agency, the White House, and policy makers.
Over the years The Cartography Center produced thousands of maps. As you might imagine almost all of them were classified. Recently in honor of the unit’s 75th anniversary, the agency has released an amazing collection of declassified maps. These collection of 130 maps and over 200 images of old cartographic tools possibly played an important role in many significant events in the world’s history.”
