Unified Incident Command and Decision Support (UICDS) is a national middleware framework to enable information sharing and decision support among commercial, academic, volunteer, and government incident management technologies used across the country to prevent, protect, respond, and recover from natural, technological, and terrorist events. UICDS is designed around data standards and the National Information Exchange Model (NIEM) to support the National Response Framework (NRF) and the National Incident Management System (NIMS), including the Incident Command System (ICS). UICDS links homeland security and emergency management organizations, from incident command at the scene of an emergency to local and state operations centers to federal departments and agencies, from intelligence fusion centers to transportation management centers to health service organizations, and many other groups. UICDS is the standards-based middleware that exposes selected data from commercial and government applications and allows relevant emergency applications to subscribe to that information in order to have more than situational awareness – UICDS enables true sharing of information among applications so that each application’s user can process, manipulate, expand, visualize, and share better and new information.
