摘要
针对网络环境和异构数据对WebGIS的体系及功能提出的新要求,分析了J2EE和ArcIMS体系结构和运行机制的特点,设计了一种基于J2EE与ArcIMS的多层分布式WebGIS系统的框架.并结合具体的项目开发实例,详细介绍了系统的逻辑层次与功能部署,重点对系统利用EJB组件实现地理空间信息与非空间信息服务的关键技术进行了阐述.
The environmental changes in network and the existence of heterogeneous data bring new requirements for the architecture and functions of WebGIS, after analyzing the characteristics of architecture and operational mechanism of J2EE and ArcIMS, a multi-layer distributed framework for WebGIS system based on J2EE and ArcIMS is designed. A specific examples of project development is given to demonstrate the logical levels and the function deployment of the system, focusing on the key technologies used in implementing the services of geospatial information and non-spatial information by EJB components.
