Abstract
The problems of digital elevation model (DEM) reconstruction from isogram maps and the arising problems are considered. An iterative algorithm based on discrete cosine transform with taking into account several nonlinear constraints is proposed. The algorithm efficiency and accuracy analysis for test and real data are performed and compared to Delaunay triangulation based method. The advantages of the proposed technique are shown.
