Inhalt:
TanDEM-X mission delivers a global digital elevation model of high quality (12 m posting) close to the HRTI-3 standard. However, when it comes to urban areas, layover effect caused by the side-looking nature of the radar satellites handicaps the use of classical multi-baseline phase unwrapping and TanDEM-X data alone for a precise 3D reconstruction. This calls for advanced SAR image processing methods and additional data. This paper demonstrates our effort of creating the global Level of Detail 1 (LoD-1) urban model using primarily the TanDEM-X data. This global building model dataset will be made open access to the community.
