As new remote sensing data and geographic information system (GIS) technology becomes available, it is increasingly possible to develop and provide effective products, services, and tools to the emergency management community. GIS technology has become increasingly affordable and provides the ability to capture, organize, manipulate, display, and analyze complex collections of geographic data and information. The Pacific Disaster Center (PDC) has historically provided decision support products and services to local, state, federal, and regional emergency managers in the Pacific Region to assist in all four phases of disaster management: mitigation, preparation, response, and recovery. The PDC’s current mission includes the integration of scientific knowledge, remote sensing data and tools, modeling and simulation technology, weather analysis, digital and information technology, and systems engineering processes in support of the disaster management community. Current activities and methods are presented in this paper. © 2002 Society of Photo-Optical Instrumentation Engineers.
