自适应型WebGIS构成模式初探

Self-Adaptive WebGIS Pattern

在元数据概念的基础上 ,分析了目前流行的WebGIS结构模式的不足 ,拓展了元数据的概念 ,提出了程序元数据的概念 ,并基于其上提出了构件灵活配置的应用分布模式 ,较好的解决了Internet环境下系统应用的灵活配置及分布式数据的共享的问题。

To implement distributed application component and data storage and access on Internet is a keystone in WebGIS research.Based on the concept of metadata,this paper analyzed the disadvantage of present WebGIS architecture,extended the concept of metadata,brought forward program metadata,and provided a flexible configuration mode of GIS components,preferably solved the problem of sharing distributed data and configuring application flexibly.
