Haze And Sun Angle Effects On Automatic Classification Of Satellite Data-Simulation And Correction

Variations in sun angle and haze level change the spectral signatures collected by multispectral scanners (MSS). This paper describes methods and computer programs that have been developed to simulate the effect of such variations and to correct for them. Simulation and correction are really the same process since correction consists of simulating a different haze level or sun angle than is actually present when the data was taken.
