卫星遥感影像中角度信息的分析利用
中国科学院研究生院,北京100039
摘要:

利用地面实测数据和NOAA卫星数据验证了地物的方向性反射和热点效应,定量分析了NOAH参据中包含的角度信息;利用多角度NOAA数据提高了地物识别精度,研究了角度信息在遥感应用中的有效性;最后,分析了常规遥感数据处理过程中太阳高度角纠正对角度信息的影响。

Analysis and Application of Directional Reflectance in Satellite Remotely Sensed Data
Abstract:

This paper proves the directional reflectance phenomena of ground objects and hot-spot effect by using fielddata and NOAA satellite data. This further proves that NOAA data has directional reflectance information. Theprecision of unsupervised classification is improved by using multi-directional NOAH data, which indicates that thedirectional information can be applied to Remote Sensing. Finally, this paper analyzes the effect of traditional remotelysensed data processing method on directional information, especially that of the sun zenith angle calibration.
