Research on the key technique of real-time aerial and marine state 3D visualization

Real time aerial and marine surveillance is one of important method which could insure the domain security of our country. In long-term period, the complex aerial and marine surveillance data didn´t have more effect visualized ways, also lack data utilize and mine means in further long views. To find a solution to this problem, this paper research how to implement real-time aerial and marine state visualization based on virtual geography environment and have the function that query and analysis aircraft or watercraft message, remind of danger factor, emphatically clarifies the key technique realization or optimize of large-range entity collision detection, route monitoring. The system have satisfied the requirement of control real-time aerial and marine state, improve the data use level of information-based.
