摘要
介绍了移动空间信息服务的概念与发展前景,分析了用J2EE构建分布式系统的技术优势,提出了基于J2EE的移动空间信息服务系统的体系结构,讨论了系统实现的若干关键技术,并开发了一个试验系统验证了其可行性。
The concept and the development perspectives of Mobile Geospatial Information Service are introduced.The technology predominance of J2EE building distributed systems is analyzed.A J2EE-based architecture is put forward for Mobile Geospatial Information Service System.Several key technologies are discussed,including geospatial information Web caching mechanism,Servlet Engine and raster map displaying.And the simple prototype system,developed based on the architecture and using the technologies,proves that the solution in this paper is feasible.
