To address the needs of emergency responders and incident commanders, a 4-D Emergency Response Tracking System (ERTS) is being developed to provide dynamic situational awareness in locating first responders and assets within building structures in urban environments. The proof-of-concept presentation will demonstrate how 3-D intelligent, interactive visual models of building infrastructure can be produced from 1-D (tabular data), 2-D (floor plans), or 3-D (CAD models) building information, integrated with location sensor(s) inputs tracking people and resources both outside and within the building structure. Structural feedback from first responders is also processed to quickly update the building structure on-the-fly. The incident commander has immediate access to this integrated, geo-referenced situation awareness through an interactive 4D Browser (fourDscape[TM]). Commercially, this 4D ERTS can be deployed to all first responder organizations and corporate departments to provide comprehensive understanding of the emergency situation as it rapidly unfolds
