Remote Sensing data processing and analysis involve multiple algorithm process procedures. Traditional Remote Sensing algorithms are tight-coupling. It is possible for the Grid Workflow to integrate distributed data and algorithms among idle computational resources in a Grid computing environment. This paper firstly introduces the workflow description language and the features of remote sensing algorithms. Then, it gives the status of workflow research and analyses the related research of Grid workflow applied to remote sensing domain. It presents the necessity to implement an GUI of dynamic Grid Workflow web portal applied to Remote Sensing information service. During the design, the authors use an 8-tuples to illustrate the relationships of the different parts of such a workflow. Finally, the authors implements the GUI of Grid workflow described.
