Abstract :
Snow surfaces in the polar regions have uniform reflecting properties over large areas. Slopes are usually low-in Antarctica, they rarely exceed 2° except in mountainous regions. Such low slopes permit simplification of the scattering law, allowing the use of an efficient algorithm for extracting height information from images
