Internet GIS的部件化结构

THE COMPONENT CONSTRUCTION FOR INTERNET GIS

在近年来的软件发展中，网络和部件化技术的进步是其重要的特征之一。软件工业的主要突破点便是软件之间的联合和部件化。为了实现ＧＩＳ信息数据在Ｉｎｔｅｒｎｅｔ上的获取、共享和发布，即实现Ｉｎｔｅｒｎｅｔ和ＧＩＳ的完美结合，作者运用Ｊａｖａ和ＪＤＢＣ开发了基于矢量图形分布式模型的、具备部件化结构的ＩｎｔｅｒｎｅｔＧＩＳ。本文介绍的矢量图形分布式模型及其实现方法，部件化结构的思想、实践和特征。

The rapid advance of networking and componentization technology is one of the most important characteristics in software development in recent year. The main breakthrough in software technology is in software cooperation and componentization. In order to realize GIS data accessing, sharing and publishing, in other words, integration of Internet and GIS, the method of component construction for Internet GIS has being developed with Vector Graphic Distributed Model, Java and JDBC. This paper introduces Vector Graphic Distributed Model and the component construction of the new Internet GIS system, including ideals, realization and features.
