随着科学技术的发展，新的探测器不断地升空，卫星光学遥感数据经历了长周期的积累和更新。如何有效地开发与利用巨量遥数据，从中挖掘出稳藏的信息和信知识化是当前面临的严峻挑战。首先分析了地面物质和结构光谱与卫星遥感信息之间的关系，建立了空间角度模型；然后以多维遥感信息的象元矢量和波段趋势面分析为基础，分析了当前用来处理光学遥感数据的商业化”最优化“算法在处理遥感数据时经出现的”欠优”结果的原因；最后，通过

With the development of science and technology, new remote sensing devices are lunched on schedule. Optical satellite data have been undergone a long time renewal and accumulation. How to reveal hidden information from huge amount of remote sensing data and let it knowledgeable is new challenge for us. In this article, first we analysis the relation between material,structure spectral and remote sensing information, formulate space angel model. Then based on pixel vector and band vector tendency face of multi-band remote sensing information, we analysis the results of“not proper”in the cases of mining some information from remote sensing data when using the software algorithms which are selected according to“the bast optimum”of the statistics. Finally, we illustrate the mathematical principles and effectiveness of algorithms that we used in mining multi-band TM data.
