DEM based shadow & layover detection using Python (Praktikantenbericht von Anita Pollner)

Kurzfassung

The generation of Digital Elevation Models (DEMs) is one of the biggest applications for SAR interferometry. While SAR DEMs generally have highly accurate landscapes with high relief energy, they are subject to shadow/layover effects originating from the acquisition geometry. In the course of a 3-month internship, a software for the identification of shadow/layover areas based on reference DEMs was implemented. Python was chosen as the programming language for this software in order to gather first-hand experience.
