| 摘 要： | 数据库技术在“结构”性数据的管理中起到了十分重要的作用，把这种方便、高效的机制用于影像数据(如遥感数据和航空摄影数据等)这类“非结构”性数据的管理，由于影像数据的海量性和数据关系的复杂性，目前还存在许多困难。本文在充分分析影像数据具体特点的前提下，提出了一种对影像数据进行数据库管理的系统体系结构。我们开发的运行系统表明，利用该方法对适感影像进行管理，可以在网络环境下，达到对超过500GB的遥感影像进行快速查询和快速访问的目的。

| Abstract: | Database technology has been important tool for managing structural data. Using this expedient and high- efficient method on non-structural imaging data,such as remote sensing data and aerial photography data,there are many difficulties which are caused by large magnitude and complex of imaging data. In this paper,we put forward a schema for managing imaging data under analyzing imaging data characteristics. The working result of imaging database system we have developed shows,using this method on imaging data,that we can implement fast query and fast browse for over 500 GB imaging data through Internet. |
