WorldDEMTM - the most accurate global satellite-based digital elevation model available today! With unique data quality and level of detail, WorldDEM facilitates a wide range of applications such as line-of-sight-analysis, hydrological modelling, satellite imagery orthorectification and much more.
Being the first global homogeneous, single-source, high-resolution Digital Elevation Model (DEM), with unique data quality and level of detail, WorldDEM facilitates a wide range of applications such as line-of-sight-analysis, hydrological modelling, satellite imagery orthorectification and much more.
The elevation model will be refined according to the customer’s needs.
Three WorldDEM products are available
- WorldDEMcore: Unedited Digital Surface Model (DSM)
- WorldDEM™: Edited Digital Surface Model (DSM) including editing of terrain features and with assured hydrological consistency
- WorldDEM DTM: Derived from the WorldDEM™ Digital Surface Model (DSM) product by removing vegetation and man-made objects to show the bare terrain of the Earth’s surface.
This high-quality Digital Terrain Model (DTM) provides a foundation layer for applications such as civil engineering (e.g. road design, Earth work calculation), the management of natural resources as well as planning and implementation of military operations (e.g. vehicle trafficability analysis, 3D terrain visualisation)
