基于CORBA/Java的分布式WebGIS的设计与应用

Design and Application of Distributed WebGIS Based on CORBA/Java

分析了传统WebGIS的系统模式及技术特点,讨论了当前几种分布式技术,提出了一种基于CORBA Java技术的三层WebGIS模式。这种模式以GIS构件形式集成分布式的GIS,实现了WebGIS资源共享。用实例说明了以CORBA Java技术来集成WebGIS的可靠性和便利性。

This article analyses system model and technique trait of traditional WebGIS, discusses several current distributed techniques, and presents a threetier WebGIS system model based on CORBA/Java. The model integrates distributed GIS system with componentbased GIS, realizes share of WebGIS resources. Lastly, it gives an application instance and illuminates the reliability and practicability of integrating WebGIS system with CORBA/Java technique.
