4
Corporation For National Research Initiatives Background The MAGIC scenario is based on applications such as mission planning and crisis management These applications need to: –locate, process, and display real-time and/or archived datasets on-the-fly –fuse multiple types of data (e.g., weather, terrain) –be able to transfer large volumes of data for interactive visualization –support a range of user capabilities (e.g., command center, mobile user) MAGIC focuses on a terrain visualization application that uses geo-referenced datasets
5
Corporation For National Research Initiatives Objectives To develop an information system that provides application users with fast, interactive access to very large volumes of remote data distributed over a wide geographic area To demonstrate the above capability in the context of a 3-D terrain visualization application
