Change detection

By Airbus Defense and Space

Solution details




Presentation Surface changes, e.g. through earthworks, soil dumping or use of gravel roads are derived by using TerraSAR-X datasets. Short term identification as well as long-term monitoring of changes on the surface are offered. This allows analysts working on electro-optical data to focus identification and interpretation on just the changed areas. Key Features Amplitude change detection (ACC): radar backscatter changes between two SAR acquisitions indicate surface changes Coherence Change Detection (CCD): radar phase changes between two SAR acquisitions indicate even little surface changes, e.g. through earthworks Key Benefits Cloud-independent detection of even subtle changes on the surface, e.g. through earthworks Cloud-independent detection of even small scaled object Semi-automatic processing allows quick delivery of results e.g. for focusing further recognition / identification of changes Product Description A minimum of two datasets is utilized for detecting even subtle changes
