Abstract: In order to improve the performance and effect of situation display for largescale data, the key technology of situation display is studied, and a system with realtime situation monitoring, historical situation replay and threedimensional target visualization is designed and implemented. The system uses data cleaning, data interpolation and data fusion to process the situation data in real time. Then the processed data is stored in the multilevel data storage system, and the data loading efficiency is improved by cache and batch data query mechanism. Finally, the system realizes 3D visualization of target and situation based on browser and GIS service. The simulation results show that the system obtains situation data quickly and efficiently, and performs situation display effect clearly and threedimensionally. It can satisfy the requirements of target analysis, situation monitoring and replay in huge simulated confrontation wargame.
Key words : situation monitoring; situation replay; target visualization; data fusion
