摘要
GIS中间件是实现多层分布式GIS应用的核心,能有效地提供各类空间信息服务,屏蔽不同空间数据源的差异性。该文以GIS中间件技术的研究为起点,提出了WebGIS中间件框架BSGIS,对BSGIS的体系结构和处理流程进行阐述,介绍了BSGIS的具体实现,并将其应用于政府道路管理系统之上,证明了该框架在实际应用中的可行性,解决了WebGIS开发复杂性高、成本大、成功率低等问题。
Being the kernel of realizing multi-layer GIS application, GIS middleware is capable of offering spatial information service efficiently and shielding the difference of heterogeneous spatial data source. After summarizing GIS middleware technology, BSGIS as the framework of WebGIS middleware is proposed and the system architecture, processing flow, realization of BSGIS is introduced. Moreover a government road information management system making use of key technologies of GIS middleware is developed to prove feasibility of BSGIS and to solve the problems of high complexity, lower cost and success rate in WebGIS development.
