Research Of GIS-based Civil Aviation Emergency Rescue System

Along with economic development and social progress, the civil aviation becomes more and more important. With continual increase of air-traffic, unavoidable mechanical failure and the sensitivity towards atmospheric conditions of aircraft, the security of civil aviation is highly challenged than ever before. The civil aviation emergency rescue is the most important part of the Aviation Safety System; possibly it becomes the basic security of air safety. Therefore, to establish an effective response mechanisms and decision-making support system for emergency rescue of civil aviation will have great significance.For the visualization requirements of the system, Geographic Information System (GIS) has been well studied. GIS, as a kind of mapping and analysis tools for the existences on the earth, it can integrate the geographic analysis functions and common database together to implement visualization.Based on the requirements, the thesis developed a well-defined emergency rescue plan according to the classification of civil emergence. Also, a system model based on GIS has been worked out; in particular several key modules have been studied deeply. Secondly, the thesis proposes an optimization strategy on shortest path algorithm, which can shorten the corresponding time to the accident, raising the system's practicability.In conclusion, this study has important theoretical and practical significance. Theoretically, it proposes a visualization design model of implementing civil rescue plan, and then it optimizes the shortest path algorithm. Practically, in accordance with the requirement, the overall construction model and framework of the system was defined, which set up a good basis to the follow-up work.
