N2 - Nowadays geospatial data acquisition systems provide vast amounts of remotely sensed information. Timely conflation, processing and fusion of such information is crucial for operations with various applications. Specifically emergency situations and disasters response, anti-terrorist attacks, crime, and fire-fighting require efficient and timely 3D visualization to support first responder decision making. This paper is devoted to investigating the potential of multi-modal/multi-temporal fusion of very high resolution spatial imagery of San Francisco, CA (USA). Quickbird, WorldView-2 and LiDAR data were used to produce an efficient 3D visualization database to be used and analyzed with the high-end 3D visualization systems Blaze Terra, TerraBuilder and TerraExplorer Pro. The use of these platforms make it possible to enrich 3D visualization with several other advanced features (e.g., timeline of events; dynamic content of GPS and telemetry data for driven vehicles, airplanes, helicopters, UAVs, etc.; displaying video on terrain including webcam streaming; geocoding). Accuracy and interoperability analysis were also in the scope of the described research. This paper outlines the methods and results of the described research. The software utilized in this work has demonstrated to be a capable tool for modeling 3D virtual cities and the management of emergencies.
