WorldDEM™ Full Resolution
Provides a worldwide, consistent, and high precision Digital Surface Model (DSM) at 12 m resolution in GeoTIFF format.
WorldDEM™ - The New Standard of Global Elevation Models. Complete pole-to-pole coverage coupled with an unrivalled accuracy and quality are the defining characteristics of WorldDEM™. The accuracy surpasses that of any global satellite-based elevation model available today and provides a reliable and precise reference layer to enhance a wide range of applications.
Dataset Availability and Refresh
WorldDEM™ is based on radar satellite data acquired during the TanDEM-X Mission. The primary goal of the mission was the generation of a worldwide, consistent, and high precision Digital Surface Model (DSM) based on SAR interferometry.
- Pole-to-pole: Global homogeneity
- Highly consistent dataset: Data collected in the period 2011 - 2015
- Accurate: 2 m (relative) / 2.5 m (absolute) vertical accuracy
Sensitive countries are excluded from download of the full-resolution product (please contact [email protected] for a release request).
