摘要：

为了高效地组织、检索分布式海量遥感数据，研究FGDC制定的遥感元数据标准草案，提出一种具有良好可扩展性的遥感编目数据模型。基于该编目数据模型，提出一种基于编目数据的分布式影像检索算法，设计并实现一个遥感数据编目检索系统，实验结果表明，该系统是有效的。

Abstract:

Focusing on the problem of effectively organize and retrieve the distributed massive remote sensing images, this paper presents a well extensible remote sensing catalogue data model based on the remote metadata standard draft which is proposed by the Federal Geographical Data Committee(FGDC). A distributed remote sensing images retrieval algorithm is designed based on the proposed catalogue data model. It accomplishes a remote sensing data catalogue and retrieval system which is successfully applied to a massive data management system.

Key words: massive remote sensing image, catalogue, data model, distributed, retrieval
