WorldDEM Full Resolution

WorldDEM™ - The New Standard of Global Elevation Models. Complete pole-to-pole coverage coupled with unrivaled accuracy and quality is the defining characteristics of WorldDEM™. The accuracy surpasses 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.

Highlights:

• 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
