基于云计算的多源遥感数据服务系统研究

摘要

Based on analysis of remote sensing image data and data usage status,a multi⁃source remote sensing data ser⁃vice system based on cloud computing was designed in consideration of the necessity and feasibility of cloud computing technolo⁃gy application in remote sensing field. The architecture and key business process of the multi⁃source remote sensing data service system are described,including remote sensing data cloud storage,remote sensing data cloud processing,remote sensing data application service and remote sensing business registration. The application of the prototype system proves that the system can protect the original data,reduce the cost of data application,and improve data sharing rate and usage rate.%在分析了遥感影像数据及数据使用现状的基础上，综合考虑了云计算技术在遥感应用领域使用的必要性和可行性，设计了基于云计算的多源遥感数据服务系统。阐述了基于云计算的多源遥感数据服务系统体系结构及关键业务流程，包括遥感数据云存储、遥感数据云处理、遥感数据应用服务及遥感业务注册组装等。最后，通过原型系统的实现验证了系统设计既能保护原始数据的安全，又能降低数据使用的成本，同时还能够提高数据的共享率和用户使用率。
