The 30m TanDEM-X products depict detailed information of the topographic height and changes over a certain time. The DEM Change Maps [1] focus on the changes that have occurred during the years separating this new coverage from the coverages acquired to generate the TanDEM-X global DEM (between 2011 and 2014). The Change Maps are available in 30m posting and show height differences between the edited first global TanDEM-X DEM and the newly acquired time-tagged DEM scenes. The TanDEM-X 30m Edited DEM [2] is a product variant of the Global Digital Elevation Model (DEM) acquired in the frame of the German TanDEM-X mission between 2010 and 2014, and has a reduced pixel spacing of 1 arcseconds (arsec), which corresponds to 30m at the equator.

The data will be accessible through the EOC Geoservice WMS and can be downloaded directly from the EOC Download Service. [3] [4]
