With the rapid development of China's civil aviation industry, the number of aircraft is increasing, the increasing scale of the airport building, accelerating the pace of construction of new airports, and at this stage the site of the airport, navigation station erected obstacles assessment still remain in the field measurements, paper painted stage, limited to two-dimensional electronic map of the airport, navigation station, obstacles, said the presentation, not only is not intuitive, and a larger workload. To solve the above problem, we Google Earth (GE) platform, flight procedures design, 3D visualization rendering, at home and abroad on the Google Earth application in the field of small, lack in many ways experiences based on only some difficulty exploratory research. The dissertation contents is divided into three parts: The first part compared the characteristics of several software platform, focusing on the functionality of Google Earth, KML file support graphic elements; analysis of the graphic elements in the KML file and aeronautical charts element mapping, demonstrating the feasibility of the software applications in the study; Finally, the system development process. The second part on the basis of a large number of studies on the navigation on the elements in the various aeronautical charts, extracting the rendering of the logical model of the elements of the sail FIG; draw a physical model of the computer can be realized and its physical-chemical, i.e. navigational database ER diagram ; and the programming model. The third section discusses the principle used in the establishment of the three-dimensional visualization scene, technology, turning leg automatically generates automatic generation algorithm and generate routes based on route node routes data management algorithms, and finally, to achieve the flight viewpoints along the route the dynamic interaction roaming. This paper is mainly to solve the following two problems, the three-dimensional display elements of aeronautical charts; Second, the route the dynamic interaction roaming technology implementation. They are also the innovation of this paper. The aeronautical charts elements of the three-dimensional reference to the conversion of the three-dimensional aeronautical charts for the two-dimensional aeronautical charts. Routes the dynamic interaction roaming, organic combination of research, database technology, the VC programming techniques as well as Google Earth platform provides a new technical ideas for the virtual flight simulation visual function. Auxiliary routes training can be applied to the ground validation and pilot training flight procedures design, combined with the study of the performance of the aircraft, and also a special program design verification (such as single failure) and experience an important adjunct.
