SummarySynthetic Aperture Radar (SAR) has currently been applied in a number of applications encompassing the use of spaceborne sensors operating at a range of wavelengths and resolutions. Results from multiple systems operating at different frequencies will often reveal different features in the exact same scene. Furthermore, the repeat-pass nature and different characteristics of existing systems gives rise to the low coherence due to geometrical and temporal decorrelation in some areas. Following the ongoing research, the TerraSAR-X data will be used in combination with different SAR sensors to improve the knowledge about the spatial composition and temporal evolution of the Earth’s surface in Bratislava and surrounding area. The aim of this project is twofold. Firstly, to fully investigate the ground stability in Bratislava area using advanced multi-temporalInSAR techniques with focus on monitoring man-made structures (buildings, bridges, dams, etc.), feasibility assessment and quality control analysis by incorporating existing ground truth data from conventional geodetic techniques. Secondly, to perform advanced mathematical strategies for filtering, edge detection and image segmentation for feature extraction and change detection in land use and land cover. The results may help to set these SAR techniques as primary tools for continuous systematic monitoring of ground and structure stability in land and risk management applications.
