RETRACTED: Using WCS for Data Service in Spatial Information System (Retracted Article)

Scientists in earth observation field often spend a lot of time on data preprocessing according to specific application targets. Using Web Coverage Service (WCS) and research on-demand data service model in spatial information system could help to improve efficiency and interoperability. It aims to integrate a large number of fundamental data pre-processing tasks into data access procedure, and minimize the time cost. This paper studies spatial data system to provide high level spatial data products to meet application request based on WCS standards. The paper introduces service module classification methods to adapter heterogeneous data exchange, and discussed data access service components and workflow control mechanism. It also conducted close examination of comparison study with traditional methods, analysis the performance results of the experiment. (C) 2011 Published by Elsevier Ltd.
