Extraction of urban elevation models from high resolution interferometric SAR images

Abstract : This article presents a method for digital elevation model extraction from high resolution interferometric SAR images over urban areas. Our algorithm, based on the use of a unique SAR interferometric couple, processes each building separately in order to retrieve the best enclosing polygonal shape, the layover area and the ground/wall dihedral structures. The ground level is extracted in parallel. In this paper, we focus on building height extraction. The specific steps are described in the paper and illustrated by examples on real data.
