摘要
针对当前遥感产品获取存在的问题,基于网格技术、面向网络的服务技术等提出了遥感产品虚拟化的概念,并对它的定义、相关技术、特点和优点进行了讨论。认为地球空间网格环境下的遥感产品虚拟化需要建立在松散耦合型的计算模式上,需要借助于面向服务的构架。同时,为了完成网格环境下服务的发布、咨询、资源调度、服务控制、服务生命周期控制等一系列关键步骤,必须采用能够与基于服务的构架和理念相匹配的软件工程方法,提出了基于多智能体的软件工程方法学实现遥感产品虚拟化的构想,并指出了遥感产品虚拟化是面向网格计算环境的未来遥感数据处理系统的发展方向。
A new concept of remote sensing products virtualization which is based on the grid technology,Web-oriented service technology,etc.is proposed,and a detailed discussion on its definition,related techniques,its properties and merits is given.It is believed that the virtualization of remote sensing products under the environment of geo-spatial grid should be built upon the loosely-coupled computing scheme and needs resort to service-oriented architecture.Furthermore,a compatible software engineering method,multi-agent based approach,is adopted in order of completing a series of key steps involved in the grid computing environment,namely,service distributing,consulting,resource managing,service controlling and service life-cycle controlling.It is pointed out that the next generation of remote sensing data processing system should be the one that can implement the remote sensing product virtualization concept.
