摘　　要：通过分析高光谱数据的特点 ,结合数据库系统开发实践 ,提出了高光谱数据集 ,包括图像、光谱、属性等 ,在关系数据库中的存储规范。结合ORACLE数据平台 ,提出了 3种高光谱数据的存储模式 ,并结合应用实例进行对比 ,分析了各自的优缺点以及适用条件。The hyperspectral remote sensing plays more and more important roles in Remote Sensing area. Correspondingly its application becomes wider and wider. Some new hyperspectral airborne and space borne sensors provide us more choice to use such data. Hyperspectral database system is very important in improving the research in remote sensing theory, quantitative study, and applications. This paper aims to analyze the characteristic of hyperspectral data and provide a standard storing rule for the hyperspectral data set in the relation database system with practice of database system development. The hyperspectral data set include the spatial, spectral and other properties data. Three storing models in Oracle database platform are also displayed here, and compared with the practical application. Finally their advantages, shortcomings and the choosing conditions are analyzed.
