Paper Abstract

The tasks of digital elevation map reconstruction from isogram maps and the arising problems are considered. An iterative algorithm based on discrete cosine transform and histogram filtering with taking into account several nonlinear constraints is proposed. The algorithm efficiency and accuracy analysis for test and real data is carried out. The advantages of the proposed technique and the perspectives of further investigations are shown.
