建模与仿真空间参考模型软件系统的设计和实现

Design and Implementation of Spatial Reference Model Software System for Modeling and Simulation

首先介绍了空间参考模型和坐标变换软件系统设计和实现的原则，并给出了软件系统的体系结构和功能模块组成。然后给出了空间参考模型部分的主要数据结构和实现代码并分析了坐标变换的策略和方法，最后给出了坐标变换的流程、主要数据结构、函数和用户接口。

This paper first introduces the principles of the design and implementation as well as the architecture and the functional modules of the software system.Then it gives the main data structures and the source codes of SRM and analyzes the strategy and methods of the coordinate conversions . Finally,ite presents the flow of coordinate conversions and also designs and implements the software including the main data structures, functions and users interface .
