面向海量遥感影像数据的管理,结合文件间的语义关系,构建面向空间数据检索应用的文件目录体系.该方法通过影像元数据概念语义关系集合运算及属性项的语义相似度计算构建部分与整体的语义映射关系,建立影像元数据概念层次关系,并构建目录体系,通过空间数据语义细化和空间对象融合、分割等过程完成影像数据集成.在此基础上,设计开发了影像元数据目录集成系统.结果表明:基于细分部分整体关系的数据集成方法能有效集成具有不同语义的影像数据集,实现了影像数据的高效共享和融合.%We built a file catalog system of data application based on the part-whole ontology of spatial relation to manage the massive remotely sensed image files effectively.Firstly we analyzed the property of images' metadata and calculated the weight for application.Secondly,we built the concept level relation,and calculated the similitude degree of the image property to build the catalog tree.Thirdly,we stored the files into the corresponding directories.Finally we designed and realized the directory experiment system.Experimental results show that our method is effective for image data's high efficient integrative management.
