基于地理信息服务的数字校园系统设计与实现
|
摘要
Web Serviees已经被作为面向服务系统体系的主要技术之一,这是因为WebServices为Internet上异构信息的共享和异构系统的集成提供了一个分布式计算方法。Web Services规范完全独立于编程语言、操作系统和硬件环境,使服务提供者和使用者之间能够保持松散关系。
OIS Web Services基于Web Services技术之上,为解决传统Web GIS不足提供可能。实现了数据类型的标准化、软件复用、平台独立性,不仅成为解决地理信息共享与互操作的重要方式,而且扩展GIS应用模式,使基于服务的地理信息技术应用不断扩展。
本文在进行数字校园系统设计与实现的过程中,以GIS Web Services理论与技术为主要支持,以方便校内外人士对校园空间信息查询、分析、管理为目的,以ArcGIS Server为支持平台,研究了数字校园系统设计与实现。从数据准备、系统设计到实现等环节的实践中,对地理信息服务有了比较深的认识,在许多细节问题的处理上,提出了诸多新思路、新方法,最终成功完成了数字校园系统建设,并结合实际应用情况对其进行了一系列优化,在实际操作中总结出了丰富的经验。
For its providing a distributed calculating method for the heterogeneous information sharing-and heterogeneous system integration on the Internet, Web services has become one of the major technoldgies of service system domain. The regulated application of Web Services completely isolates from program language, operating system and hardware environment, and keeps a loose relation between service providers and users.
GIS Web Services bases on the Web Services technology, deals with the weaknesses of Web GIS. GIS Web Services realizes the standardization of data type, software reuse and the platform independence; actually it has not only become an important way to deal with geographic information sharing and interoperability, but also extended the application mode of GIS, basing on the development of GIS technology.
With the process of the design and implement of digital campus, digital campus system grounds on the theory and technology of GIS Web Services, aims to make it convenient for people inside and outside campus to search, analyze and manage campus spacial information. In the practice of data preparation, system design and implement, in this article promoted some new approaches and methods, and finally accomplished the construction of a digital campus system. In accordance with application, optimized the system and summarized some experience in practice.
