[Thermal mosaic of World Trade Center site, 10/20/2001]

No. 5 in a sequence of thermal mosaics of World Trade Center site taken on October 20, 2001, more than a month after the September 11 terrorist attack upon the site. These mosaics combine multiple thermal images, which were imported into a Geographic Information System (GIS), placed atop current orthophotographs of the World Trade Center site, and had temperature values colorized. These overlays helped emergency personnel plan work and avoid areas that remained dangerously hot.

In this image, the gap immediately to the right of the footprint of 2 World Trade Center was formerly occupied by 3 World Trade Center. The remnants of 4 World Trade Center are immediately to its left.
