虚拟地理环境计算框架及其关键技术研究
Study on VGE Computing Architecture and Key Technologies
【摘要】 分析了地理计算和虚拟地理环境(Virtual Geographic Environment,VGE)的特点及问题,探讨了网格技术在虚拟地理环境计算中应用的优势,设计了基于网格服务的虚拟地理环境计算框架并重点研究了计算框架下的VGE数据协同和计算服务运行机制,最后结合一个实例建立了系统原型并进行了说明.
【Abstract】 Characteristics of geocomputation and virtual geographic environment(VGE) are analyzed and superiority of applying Grid technology to VGE computation is discussed.Then VGE computing architecture is designed based on grid service.VGE data collaboration and computing service implement mechanism are also discussed in detail.Finally,a prototype system is build and an experiment is implemented.
