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.
