Description
This series consists of digital aerial photographs, thermal imagery, flyover simulations, and raw Geographic Information System data documenting conditions at the World Trade Center site (commonly referred to as "Ground Zero") immediately after the terrorist attacks of September 11, 2001 (widely referred to as "9/11"). This data was created by EarthData, a mapping services firm working under contract to the State Office for Technology, and was relayed to federal, state, and local government emergency personnel working at the World Trade Center site.
