高光谱数据在Oracle中的存储及应用技术研究

Research on Storing and Analyzing the Hyperspectral Data in Oracle Database

高光谱遥感作为遥感的前沿技术,正在得到日益广泛的应用,其数据积累日益丰富。随着定量化遥感渐渐成为关注的核心,很多领域都越来越迫切地要求建立一个能存放高光谱数据、功能性强、使用方便、易扩展、与本领域应用相结合的数据库系统。针对高光谱数据特性以及处理和管理的需要,文中提出了基于Oracle数据库的面向对象的高光谱数据管理模型,从而便于高光谱数据的存储、管理、查询;并基于高光谱数据库进行了SAM分类实验,验证了该模型的有效性。

As one of the newest area of Remote Sensing technology, the hyperspectral remote sensing is used more and more, correspondingly the data are richer and richer. As the quantitative remote sensing has been more concerned, a strong powerful convenient expandable database system, which can store hyperspectral data and is combined with application function, is badlly needed by the related areas. This paper aims to analyze the characteristic of hyperspectral data and provide a data-manage prototype system of spectral library based on oracle database development. Experimental results of SAM class show that the prototype system can easily manage, storage and query hyperspectral image data and has good concurrent performance.
