基于工作流的图像处理网格平台及其遥感应用

Workflow-Based Image Processing Grid Platform and Remote Sensing Application

图像处理网络平台基于工作流实现资源共享和协同计算,是一个灵活、动态的图像处理问题解决环境.其中,网格工作流技术可满足灵活多变的应用需求,通用服务请求代理能实现异构网格服务的简单调用,动态工作流模型利用具有较强描述功能的扩展有向无环图建模语言进行定义.该平台已成功地应用于遥感图像处理.

To facilitate the requirements of remotely sensing applications, a workflow-based image processing grid platform is built to support resource sharing and cooperation. It is a flexible and dynamic image processing problem-solving environment. Grid workflow technology can facilitate agile requirements of various applications, general service broker can invoke heterogeneous grid services simply, and workflow models are defined by the more operable extended directed acyclic graph language. Remote sensing applications have been applied on the platform successfully.
