WebGIS技术在环保系统开发中的应用现状及对策

The Status and Strategy of WebGIS Technique Applied in Environmental Systems Development

网络技术和GIS技术共同应用于现代环保,使得环境保护驶进信息化的高速公路从而快速实现了GIS信息的交流,并分享GIS数据及其成果。但是,在技术的高度融合过程中出现了很多问题,如WebGIS的技术形式多样,技术不成熟,平台不统一,没有形成模块化;GIS地图数据量大在网络上的反应速度慢;基于网络的B/S结构没有组件式开发C/S反应灵活;数据保密性要求较高等问题,给WebGIS的广泛应用提出了挑战。本文针对这些问题进行了逐一分析,并提出了解决的一般方案。

Network technique and GIS technique applied to modern environmental protection,promotes the development of environmental protection into the information highways,which makes it possible to share the result and data of GIS.However,problems such as the diversity of technique,immaturity of technique,inconsistency of platform,and not forming functional modules,occur in the process of high degree integration of technique.The large amount of data makes GIS map slow in response speed,B/S based structure is not as flexible as C/S based structure,and the confidentiality of GIS data is higher than that of normal data.All these challenge the application of WebGIS.This paper analyses these questions one by one and puts forward respective solutions.
