Throughout history mankind has borne witness to various forms of calamities, some natural while others man-made. Events such as the 9/11 Attacks, Hurricane Katrina, the Loma Prieta Earthquake, etc. are examples of these. These disasters are potentially life threatening, hazardous, and require immediate response. In such events, rapid and informed decisions need to be formed based on available data. Disaster recovery systems should assess crisis situations and generate effective response plans in a timely fashion. The ability to make sound, critical judgements is dependent on the reliability and accuracy of the information gathered. Hence, a measure of the amount of certainty data is imperative. To this end, DiRecT (Disaster Recovery Tool) has been developed. This application addresses the crucial issue of Uncertainty Visualization as it applies to emergency response. Uncertainty Visualization refers to the process of providing visual cues that aid the viewer in understanding the inherent amount of uncertainty present in data. DiRecT incorporates uncertainty measurements and visualization as key elements in an integrated system for disaster recovery, providing assistance to time-sensitive and mission-critical disaster scenarios.
