TanDEM-X DEM Change Maps Stacks: Towards TanDEM-X 4D

Kurzfassung

The TanDEM-X mission acquires data used for the generation of Digital Elevation Models (DEMs) since 2010. From this data two global DEMs are already generated or in generation. The DEM acquisitions used for new TanDEM-X DEM 2020 are also used to generate TanDEM-X DEM Change Maps. Furthermore, the DEM Change Maps can be combined with the additional TanDEM-X DEM datasets and used for the generation of TanDEM-X DEM Change Map Stacks. This paper presents these new products on the basis of an exam ple of an open-pit mining area in Australia. Additionally, the potentials and challenges of the DEM Change Map stacks are presented.
