Interactive Visualization of National Airspace Data in 4D (IV4D)

摘要

This Final Technical Report discusses the accomplishments of an effort to support NASA and FAA goals for visualization of the National Airspace System (NAS) to aid the analysis of proposed changes to increase its capacity and meet future needs. The Air Force Research Laboratory (AFRL) is developing a JView-based visualization tool, known as the Viewer, for visualizing objects and results from NASA's ACES (Airspace Concept Evaluation System) simulation application. IV4D (Interactive Visualization in 4-D) was developed as a plug-in to the Viewer. It employs a combination of heuristics and visualization defaults in order to search for entities to visualize, and then to display them with minimal user selection. IV4D makes it easy for aeronautics researches and others to display flight trajectories, airspace boundaries, weather, and more, with data coming from multiple sources, including multiple software and simulation applications. IV4D is designed to work with most forms of NAS state data, concentrating first on data representing the most common elements of objects within the NAS - positioned still and moving objects; that is, concentrating on objects situated by latitude, longitude, elevation, which are present for a defined period of time.
