数字城市规划中基于SOA架构的SIT集成模式研究

Study on SIT Integration Schema Based on SOA for Digital Urban Planning

针对空间信息技术(SIT)和数据库等技术在数字城市规划中的应用集成问题进行分析,提出数字城市规划中基于面向服务体系架构的空间信息技术集成模式。该集成模式以统一的数据中心为基础,消除了业务软件的异构与差异性,提高了数字城市规划中业务间数据传递和共享能力。建立的集成信息系统具有较强的开放性和可扩展性,实现了业务系统根据信息化技术的发展进行相应的变化和扩充需求,较好解决了企业级数字城市规划信息平台中数据交换和共享的难题。

Aim to solve the problems of integration of spatial information technology （SIT） in digital urban planning; this paper put forward the SIT integration schema in digital urban planning based on analyzing the features and advantages of service-oriented architecture （SOA） and discussed the integration of various spatial information technologies and database in digital urban planning according to this integration schema. The integration schema was constructed on the uniform data center,and it could solve the problems of data exchange and sharing and then to improve the capability of data transform and sharing between oper- ations. At the same time,the constructed operation platforms under this framework had better extendable and open features can make operation system changed and extended according to the development of information technology, and can eliminate the heterogeneous and difference between operation software, then ultimately satisfy the demand of interoperation and data sharing of digital urban planning.
