摘要
分析了现有WebGIS系统中常见的两种体系结构,对其中存在的问题进行了深入的讨论,指出无法实现异构空间数据的共享与功能上的互操作是阻碍WebGIS进一步发展的两大障碍.开放式的WebGIS是今后的发展方向,本文基于最新的Web技术提出一个七层结构的分布式空间信息服务互操作模型,为解决现有WebGIS中的缺陷,构建以分布式空间信息服务为核心的基础信息服务平台做了理论上的探讨与研究.
This paper analyzes two popular architectures in the existing WebGIS and discusses the existing problems thoroughly. The insufficiency in sharing geospatial information and function interoperability between different systems are the biggest obstacles to block the development of WebGIS. The sevenlayered interoperation model of distributed geospatial information service based on the newest web technologies is proposed in this paper to solve the main problems of present WebGIS. Finally, a complete discussion and research are made theoretically, which aims at constructing a fundamental information framework based on distributed geospatial information service.
