摘    要:万维网地理信息系统(Web GIS)是地理信息系统(GIS)发展的一个重要方向,它具有访问范围广、平台独立性高、系统成本低且操作简单等特点。本文在介绍组件对象模型,分布式组件对象模型(COM/DCOM)技术的基础上,结合Web GIS开发中可能遇到的瓶颈,把二者结合,将一个基于组件的四层开发模型进行应用,解决系统在物理以及逻辑上的独立,为Web GIS中存在的安全、通信速率及GIS应用二次开发等难题的解决提出新方案,以达到Web GIS开发的时间和效益的双结合。

关 键 词:万维网地理信息系统  组件对象模型  分布式组件对象模型  应用

Abstract:World wide web geographic information system (WebGIS) is an important direction to geographic information system (GIS). Although development time is not very long, it has formed large-scale industries because of being promoted by supporting technology, such as mapping technology and computer technology. WebGIS has a wide range of visit, high platform indepondence, low system cost, and ease of clinical manipulation, which have been a main direction of GIS development. On the basis of component object model (COM) and distributed component object model (DCOM), combining probable bottleneck in WebGIS development, a four-component-based model of development was applied to realize combination of time and effective.
Keywords:world wide web geographic information system  component object model  application
