基于J2EE的网络地理信息系统的设计与实现

The Design and Implementation of WebGIS Based on J2EE

WebGIS(网络地理信息系统)实现了GIS信息数据在Internet上的获取、共享和发布。首先分析了当代WebGIS的运行模式和基于J2EE开发WebGIS的优势及其体系结构。然后设计和实现一个组件化的、多层的、分布式的WebGIS系统———DigitalNWU,指出了该系统具有的优点。

WebGIS(Web based Geographic Information System)implemented the acquisition,share and issue of the information and data of GIS through the Internet.Firstly,the run models of the current WebGIS and the advantages of the WebGIS which was implemented with J2EE were analyzed in this paper.Then the component,multitiers and distributed WebGIS--DigitalNWU was designed and implemented.At last this paper enumerated all advantages of DigitalNWU.
