摘要
随着网络技术的发展,地理信息系统(GIS)作为一门综合的交叉学科也得到了进一步的发展,网上地理信息服务已经成为GIS应用的热点。为此着重阐述用J2EE设计和开发网上地理信息发布服务的基本思想和方法以及实现网上地理信息资源的浏览、共享、查询和分析处理等功能。提出基于J2EE的网上地理信息发布服务的体系结构,介绍基于JavaBean的地理信息客户端、GIS Servlet引擎、GIS EJB组件的设计。结合实例验证该设计思想的合理性和开发方法的正确性。
With the rapid development of Internet technology,GIS as a compeitive intersectional domain also makes more progress,and geo-spatial information based on Internet has being a focus application of GIS.In this paper,firstly the author expound emphatically the general idea and method of designing and developing geo-spatial information services based on J2EE.Secondly the functions of geo-spatial information based on Internet are implemented,such as browsing,sharing, query and analysis,and the structure of geo-spatial information services base on J2EE is put forward.Thirdly the GIS client server based on JavaBean,the GIS Servlet engine and the GIS EJB component are introduced.Finally,this paper integrates the example to prove the feasibility and the correctness presented above.
