NSF And 9/11 >> Mapping the Site
A team from Georgia Tech led by engineer David Frost collected damage data near Ground Zero using an innovative system that included Palm handheld computers. Frost and his colleagues originally developed the system, known as PQuake, for earthquake response.
PQuake allows many researchers to simultaneously collect and input Global Positioning System coordinates, digital data and photos into one format. This capability ultimately produces near-real-time mapping of the extent and severity of damage at a disaster site. The small devices generate detailed maps in hours rather than days, giving recovery workers critical information that applies to planning, operations and safety.
