WorldDEM™ Streaming
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. WorldDEM4Ortho is a 24m elevation information layer optimised for the orthorectification of high-resolution (HR) and very high resolution (VHR) optical satellite imagery. WorldDEM4Ortho is the most consistent, homogenous and accurate elevation model for high-quality image orthorectification on a global scale.
WorldDEM 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.
The WorldDEM Streaming service provides access to the global WorldDEM database via two protocols. These protocols include WMTS for free unlimited access to relief map viewing and WCS for accessing the data in full resolution. A weblink for WorldDEM Streaming is provided upon order receipt allowing direct connection to your GIS. API integration into own applications is possible. The consumption can be monitored and tracked online.
This offer comes with a yearly subscription model. Several subscription ‘Packages’ are available suiting to your needs starting at just €2,500/year.
| Product | Description |
| WorldDEM | A 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. |
| WorldDEM4Ortho | 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. |
