基于GIS的参数化飞行程序辅助设计系统

GIS-Based Parameterized Computer Aided-designing Flight Procedure System

文章结合参数化技术设计并实现了基于GIS技术的飞行程序辅助设计系统(ComputerAided-designingFlightProcedureSystem,CAFPS),建立起CAFPS分层次的参数化模型及总体结构。该系统以MapGIS作为支撑平台,采用面向对象技术实现系统各功能模块,并将一种求解二维几何约束的方法和GIS平台的图元实体的数据结构特点结合起来进行参数化求解。CAFPS可有效提高机场建设和飞行程序设计的效率。

This paper designs and implements a Computer Aided-designing Flight Procedure System （CAFPS） which is based on the parameterized technologies and GIS technologies,and whilst,devises the layered parameterized model and the whole architecture of the CAFPS.The CAFPS implements every functional module through the object-oriented programming with MapGIS as support platform.In addition,we carry through parameterized resolving to utilize the method which combines the solving of 2D geometric constraint and the characteristics of GIS platform such as the data structure of graphic primitive.The CAFPS will improve the efficiency of the airport building and the flight procedure devising.
