T-Kartor Group Timeline


This is 1943, inside The Globe Building. The US Army leased 3 floors here and installed the Aeronautical Charting Service. The spy film from the airplanes was shipped to The Globe, developed and triangulated into maps. The maps were printed here and sent back to the battlefield.

The Aeronautical Charting Service was in the building until 1958. It evolved to become NGA (National Geospatial Intelligence Agency). T-Kartor Group does mapping for NGA.
