Airbus Defense and Space’s edited WorldDEM database, along with the WorldDEM4Ortho dataset, are now available for streaming. WorldDEM is a single-source digital elevation model.

According to the company, access to the WorldDEM and WorldDEM4Ortho of the entire Earth’s landmass facilitates a wide range of applications, such as line-of-sight analysis, hydrological modeling, satellite imagery orthorectification and more.

The WorldDEM dataset corresponds to a hydro-enforced digital surface model with water surfaces of lakes and reservoirs set to a single elevation. Rivers and canals are flattened with monotonic flow, oceans are set to zero and coastal infrastructure features are removed.

WorldDEM4Ortho, which is based no the global WorldDEM dataset, is tailored to orthorectification of high and very high- resolution optical and radar satellite data. According to Airbus, it enables corrections of all distortions induced by the topographical variations of the Earth’s surface and the satellite orientation when acquiring the image.

Airbus Defence and Space is a division of Airbus responsible for defence and aerospace products and services.
