SAR interferometry has been extensively used for the generation of Digital Elevation Models (DEMs). In particular, the TanDEM-X stands out as a dedicated mission designed to provide very accurate elevation information in a global scale. From October 2014 to December 2015 the mission endured its science phase during which interferometric data with increased baseline were acquired, thus allowing for the retrieval of local DEMs with even higher vertical accuracy than the standard TanDEM-X products. This paper present first results regarding the generation of DEMs using the large baseline experimental TanDEM data, including a preliminary evaluation of the obtained accuracy.
