WorldDEM™ is a 12m Digital Surface Model (DSM) with unprecedented quality, accuracy and coverage. WorldDEM™ provides a reliable and precise reference layer to enhance a wide range of applications.

Product Description 

Pole-to-pole coverage coupled with unrivalled accuracy and quality - these are the defining characteristics of the WorldDEM™. The accuracy surpasses that of any global satellite-based elevation model available today and defines a new industry standard. WorldDEM™, a global DEM, is derived from TerraSAR-X and TanDEM-X radar satellite data with vertical accuracy down to better than 4m at 12m grid spacing. The product is available as Digital Surface Model with or without flattening of water bodies and as Digital Terrain Model representing bare Earth elevation. WorldDEM™ (edited DSM) is available off-the-shelf.

Integrating WorldDEM™ as a reliable and precise reference layer into operations and applications provides for a single confidence scale and enhances the performance of a wide range of systems and equipment. The dataset is enhanced responsiveness and efficiency for defense & security missions with improved flight safety and efficiency and high-quality image orthorectification. It is also for reliable planning and operation of exploration projects and timely intelligence for emergency response and global availability that enhances international cooperation and cross-border mission planning.

WorldDEM CoreThis Digital Surface Model (DSM) represents the surface of the Earth including buildings, infrastructure and vegetation. This unedited DSM is output of the interferometric processing without any refinement (editing). This product usually contains radar specific artefacts, voids and can include processing artefacts.
WorldDEM™This product is a refined DSM ensuring hydrological consistency, i.e. flattening of water bodies and consistent flow of rivers, and includes editing of shore- and coastlines.
WorldDEM DTMDigital Terrain Model (DTM) representing bare Earth terrain without obstruction features above ground.
WorldDEM BundleIncludes both WorldDEM™ and WorldDEM DTM.
Quality LayersThese auxiliary information layers (Amplitude Mosaic, Filling Mask, Editing Mask, Water Body Mask) are generated during the production process and are available as raster data in GeoTIFF format.

Please note 

Minimum order size (per AOI): 100km². Width of AOI ≥ 1km for WorldDEM™. Width of AOI ≥ 2km for WorldDEM DTM. Width of AOI ≥ 2km for WorldDEM Bundle. Additional DEM variants, formats, or re-projections available on demand and subject to customized pricing.
