Storage Technology Research on Three Dimensional Flight Track Based on KML and SQL Server

For the asymmetry of real time flight information among civil aviation departments and between civil aviation and popular users, the users satisfaction reduced. A research on storage of 3D flight track was proposed combining KML and SQL Server. Firstly, SQL server is applied for storage of existing real time flight data and authorized users information. Then, the KML file is written to present dynamic 3D track. Finally, a website was deployed for authorized user to download the flight data. The research was realized and indicated that it increases data sharing between civil aviation sections and users, and decreases the risk of data leakage.
