Change Detection and Monitoring related to Geospatial / Image Intelligence requires temporal dense and reliable provision of information about continuous activities over a longer time period.
As an active spaceborne sensor TerraSAR-X delivers reliable and timely change information supporting large area overview as well as targeted observation of hot spot areas.
Geospatial / Image Intelligence / Interferometric Coherence Change Detection
Forests are the lungs of our planet, providing carbon sinks that play a key role in regulating climate and the water cycle. Sustainable management of forest ecosystems is essential and TerraSAR-X imagery can support a detailed assessments of changes in forest resources. Automatically extracted change layers of repeat pass imagery deliver up-to-date information on changes in forest cover even of small extent due to e.g. illegal logging, forest fires or storm damage.
Forestry / Amplitude Change Detection
In case of natural and man-made disasters satellite remote sensing data becomes a crucial source of information for the relief units. TerraSAR-X supports mapping of a disaster’s spatial extent, the assessment of damages to population and infrastructure (transport, energy etc.), theidentification of hot spot areas and the support of an efficient coordination of evacuation and rescue measures.
