摘要
随着遥感技术的不断发展,人们对影像分辨率要求越来越高,获取的影像数据量越来越大,如何安全高效地应用与管理大影像资料已成为当前迫切需要解决的问题。本文针对影像数据管理与应用方法特点,提出利用底层OCI接口起到Oracle引擎的作用,采用Oracle升级后新增InterMedia组件中ORDImage类型存储影像,结合影像数据库开发的相关技术,实现了遥感影像库的基础功能模块,为建立安全高效的遥感影像库提供了技术支持。
With the development of remote sensing technology, more and more the remote images have been ob- tained, so the mass image data managed effectively is one of key tasks for the application of remote sensing. According to the characteristics of the mass remote sensing image data,this paper puts forward that the ORDImage of Oracle InterMe- dia is used as Remote Sensing Image storage of data types, the bottom OCI interface is used to access Oracle, combining with image database related technologies, at last it realizes the basic function modules, and provides the technical support for establishing the safe and efficient remote sensing image database.
