| Abstract [eng] |
At the time when the number of flights is increasing and new initiatives for air traffic control (ATC) optimization are being implemented, there is a need to apply technological innovations to improve ATC systems. One of such innovative projects is the EU FP7 SKY-Scanner project, which is aimed at the use of LIDAR (light detection and ranging) for aircraft tracking. This paper investigates user interface design for the decision support system (DSS) based on LIDAR and RADAR data fusion. An overview of recent developments in the field of visualization for ATC shows that traditional 2D visualization is no longer sufficient, and pure 3D visualization has some significant drawbacks, so there is a need to integrate 2D and 3D visualization. One of the tasks of the DSS is to check if the airplane trajectories satisfy the requirements denned in the approach and departure procedures. This raises a problem of knowledge representation - procedures are depicted in charts, and knowledge from the charts must be represented in the DSS algorithms. Thus the research covers two fields: user interface and knowledge representation. We decided that it is important to visualize the requirements for trajectories. Two alternative interface approaches are proposed (one based on 2D, and one based on 3D), in which these requirements are visualized using 2D projections (walls). Also alternatives for visualizing other objects (airplanes, their real and projected trajectories, topography) are presented. |
