Abstract

In flooded elevated regions, mapping and differentiating the shadow-layover pixels of input SAR image from the overall inundated region is a major challenge which is not addressed in earlier studies. This paper will brings out the details about a DEM based SAR image analyzing techniques that can help in identifying the pixels of shadow/layover regions of input SAR image. The outcome of the proposed technique have been verified with eight different RADARSAT-2 SAR scenes which have been acquired during various flood events of India and the results of one of the image has been discussed in this paper.
