A case study of remote sensing information model simulation and description

This paper has study the description and simulation computation methods of remote sensing information model, and try to propose a more available way to solve this problem. This paper presents our research works on the description and simulation methods of remote sensing information model: the service on demand method provides a basic methodology of model analysis, the semantic relationship description of information processing procedure gives the basic knowledge of resource selection and matching based on user´s demand, and the hierarchical mapping method of remote sensing information model shows the transformation from abstract model to concrete service chain, which can help to design the executable workflow of model simulation and computation.
