基于Windows DNA 框架的GIS软件结构初探

摘要

As a emphasis in the field of GIS,GIS software arch itecture is increasingly discussed.This paper introduces Windows DNA,then focuse s on a framework of GIS software architecture.It's logical structure and real st ructure are also concerned.This kind of GIS software architecture can easily enc apsulate difference structure and difference location data of GIS into a compone nt and quickly add and drop a GIS function component. It is a shortcut to develo p a GIS software.%GIS软件结构体系作为GIS研究的一个重点，日益受到人们的重视。本 文在简介Windows DNA结构体系后，提出了一种GIS的软件结构框架，并详述该结构的逻辑组 成及物理配置。这种结构的GIS软件可以封装异构异地GIS数据和快速的添加及删除GIS功能 组件，是快速开发GIS软件的一个途径。
