WorldDEM

A complete pole-to-pole coverage is one of the distinguished features of our WorldDEM. Coupled with an unrivalled accuracy and quality, these are the defining characteristics of this unprecedented dataset.  The WorldDEM accuracy surpasses that of any global satellite-based elevation model available today and defines a new industry standard. WorldDEM provides a reliable and precise reference layer to enhance a wide range of applications.

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. Key features include:

  • Pole-to-pole: Global homogeneity
  • Highly consistent dataset: Data collected within 3 years only
  • Accurate: 2m (relative) / 4m (absolute) vertical accuracy in a 12m x 12m raster
  • Two Models: Digital Surface Models (DSM) including the “first surface” elevations & Digital Terrain Models (DTM) representing the bare Earth elevation available
