CORS在线服务系统开发探讨

Discussion on Development of CORS Online Service System

结合青海CORS建设及服务发展现状,针对CORS在线服务系统进行开发设计探讨,对CORS在线服务系统功能进行详细分析设计,提出系统构架方案,将系统划分为表现层、业务逻辑层、数据访问层。并对系统各组成部分实现功能作较详细的阐述。最后,针对对用户数据使用、GPS数据预处理、坐标系统转换、高程系统转换等核心功能作出了具体的设计方案,对软件实现方案与系统集成方法实现全面阐述。

In this paper , combined with the development status of Qinghai CORS construction and service .According to the CORS on-line service system development and design study .On the CORS online service system in detail design .Put forward the system frame-work.The system is divided into the presentation layer , Business logic layer , Data access layer .And make a detailed discussion on the various components of the system functions .At last, the specific design proposal was proposed in view the core function , such as the use of user data , GPS data preprocessing , coordinate system conversion , elevation system conversion and so on .At last the soft re-alization and system integration method were elaborated .
