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...
This paper deals with the fusion of TanDEM-X raw DEMs in ascending and descending pass over Mumbai test area and enhance its quality. Before applying fusion method, a robust layover and shadow map has been calculated in ITP using TanDEM-X DEM and the corresponding slant range image. The selection of optimum weights for fusion has been based on height error map calculated from interferometric coherence...
