B/S多层结构的湖泊数据库WebGIS服务系统的设计与应用

B/S多层模型是计算机网络软件工程领域内的一个趋于成熟的系统设计思想。以多层模型的思想构建We-bGIS可以解决系统深层次应用开发的诸多问题,已成为当今GIS研究热点之一。湖泊科学数据库WebGIS服务系统旨在促进数据共享,为科研工作者提供基础数据支持。本文在分析比较几种国内外数据发布系统基础上,以数据仓库的理念为指导,设计了B/S的多层体系结构湖泊数据库WebGIS系统。前台利用了动态服务器主页(ASP)技术,Web服务器采用Microsoft公司的Internet Information Server(ⅡS)。中间层采用SuperMapIS地图发布引擎,后台数据库采用了空间数据库引擎用于管理SQL SERVER企业数据库中存储的海量数据。本文围绕系统构建过程中所用到的方法和技术,探讨了B/S多层结构WebGIS的应用和实现。

Lake Database WebGIS Based on Multilayered B/S Structure System

Multilayer Brower/Server model is a domain tend to the mature system design thought in computer network software engineering. Constructing WebGIS by the multilayered model thought is possible to solve many problems system deep level application development,hence it has become one of the GIS research hot spots. The lake scientific database WebGIS service system aims at promoting data sharing and providing basic data support for the scientific research workers. Based on the analysis of the comparison of the several kinds of domestic and foreign data issue system,taking the data warehouse idea as an instruction,this paper has designed lake database WebGIS system with the aid of multilayered B/S model. The onstage used the active server page (ASP) and the Web server used Microsoft Corporation Internet Information Server (ⅡS). The intermediate level used the SuperMapIS as map server,and the space database engine is used in the magnanimous data which managed SQL SERVER. This article,focusing on the method and the technology used in the process of constructing the system,has discussed the application and realization of WebGIS based on multilayered B/S model.
