Abstract :
An improved algorithm is developed for correcting the topographic impact on satellite imagery. The authors consider variation of illumination in different Sun-facing aspects in calculation of a correction parameter and take it as a key element in the modified correction algorithm. The corrected results show the effectiveness using this approach
