TanDEM-X WorldDEM – Reaching New Heights

The German radar satellite, TanDEM-X, is in the process of generating a global Digital Elevation Model – WorldDEM – of unprecedented quality, accuracy and coverage.

  • Vertical accuracy of 2m (relative) and 10m (absolute)
  • 12m x 12m raster
  • Global homogeneity
  • Highly consistent dataset as a result of an initial global data collection window of 2.5 years and the opportunity to continue to collect locally beyond the initial collection period
  • No need for ground control information due to the high geometric precision of German sensors
