Static 3-D city models are well established for many applications such as architecture, urban planning, navigation, tourism, and disaster management. However, they do not represent the dynamic behavior of the buildings and other infrastructure (e.g. dams, bridges, railway lines). Such temporal change, i.e. 4-D, information is demanded in various aspect of urban administration, especially for the long-term monitoring of building deformation. Very high resolution spaceborne Synthetic Aperture Radar (SAR) Earth observation satellites, like the German TerraSAR-X and TanDEM-X provide for the first time the possibility to derive both shape and deformation parameters of urban infrastructure on a continuous basis.
