WorldDEM4Ortho DSM layer in GeoTIFF format.


WorldDEM4Ortho is an elevation information layer optimized for the orthorectification of high-resolution (HR) and very high resolution (VHR) optical and radar images. WorldDEM4Ortho is a digital elevation model based on the WorldDEM™ product offered by Airbus Defence and Space which covers the entire land surface of the Earth. WorldDEM4Ortho is a DSM-like product with urban areas leveled down to ground level, thus minimizing distortions in the orthorectified image. Ideally suited for DRS and satellite operators and anyone wishing to orthorectify their imagery.
