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。
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.
