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.

WorldDEM™ key features:

  • 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

Your advantages with WorldDEM™:

Compliant with industry standards - regulation  - Icon

Standardised DEM for any spot on Earth at the same quality

Available Globally - Icon

Allows closing gaps with high accuracy in areas where no adequate DEM exists to-date (cf. SRTM)

High quality & Reliability - Icon

Improve the performance of globally operating navigation systems and applications

Elevation8 - Large-Area DEMs at a High Accuracy

Elevation8 is derived from SPOT 6 and SPOT 7 stereo and tri-stereo optical satellite data and provides an optimised fit for the needs of mapping or oil & gas applications, particularly when large-area coverage is required.
