| 摘 要： | 传统的遥感影像数据库采用关键词匹配的方式进行查询,导致查询语义的缺失,通过将本体和Compass搜索引擎引入到遥感影像数据检索,可提高查询的查全率和查准率,提高查询的效果。文章提出了基于语义的遥感影像数据检索解决方案,构建了一个关于遥感数据共享的应用本体,并基于此本体初步实现了遥感数据检索系统,从而证明了该方案的可行性。

| Abstract: | By the introduction of ontology and Compass search engine to remote sensing image data retrieval,query recall and precision could be improved,and thus improve query results.This paper presented a solution of semantic-based remote sensing image data retrieval,the remote sensing data sharing application ontology is constructed,the remote sensing data retrieval system based on ontology is initially realized,and thus proved the feasibility of the scheme. |
