| 摘 要： | 遥感影像数据是国土资源管理的重要基础数据，具有多源、异构、海量、多时相的特点，在数据组织、存储、管理与服务方面具有特定的技术需求。本文针对国土资源遥感影像数据集中管理的情况下，结合数据中心在线、近线和离线的多级存储体系架构，提出了开展多源、异构影像数据分级存储与数据迁移规则的研究，依据影像数据的产品链与生命周期，提出了分级存储的原则、价值评估要素、分级存储的策略与方法，同时提出了基于不同级存储上影像数据之间的迁移规则，对于数据中心开展多源、异构、海量影像数据的高效组织、存储，降低影像数据的运维成本，提升影像数据的应用效率具有指导意义。

| Abstract: | RS image data is an important data source for land and resources management and service. Its characteristics of multiple heterogeneous sources, heterogeneous organization, large-volume and muhiple time versions make it peculiar in data organization, storage, management and service. Focusing on land and resources RS data centralization, this paper put forward hierarchical storage and migration rules based on online storage, near-line storage and offline storage in land and resources data center. According to the product chain and life cycle of RS image data, this paper put forward the principles, evaluation factors, tactics and methods of hierarchical storage. Also, this paper studied migration rules of RS image data in different storage type. These studies could give some tips for efficient organization, storage, cutting down maintenance costs, promoting management and service efficiency of multiple heterogeneous sources, heterogeneous organization, and mass RS data. |
