Abstract

TanDEM-X enters a new level of detail and accuracy for DEMs on a global scale. The vertical height specification for the TanDEM-X mission foresees a 90% point-to-point error of 2 m (4 m) for areas with predominant terrain slopes smaller than 20% (greater than 20%). Thus monitoring of the interferometric capabilities and the processed DEMs is essential. Key parameters as the interferometric coherence, phase unwrapping indicators, and relative vertical height accuracy are considered. This paper discusses the quality from the first year of DEM acquisition and presents a strategy for identifying areas with insufficient performance.
