A change detection approach to flood mapping in urban areas using TerraSAR
Very high-resolution Synthetic Aperture Radar sensors represent an alternative to aerial photography for delineating floods in built-up environments where flood risk is highest. However, even with currently available SAR image resolutions of 3 m and higher, signal returns from man-made structures hamper the accurate mapping of flooded areas. Enhanced image processing algorithms and a better exp...
متن کاملObject-oriented Detection of Urban Areas from Terrasar-x Data
Urban environments represent one of the most dynamic regions on earth. Even in developed countries the yearly conversion of natural or agricultural space into residential, industrial or transport areas frequently exceeds 100 ha. Due to these rapid changes in landuse short-term data collection is demanded. Thus, remote sensing satellites and particularly the new German radar system TerraSAR-X wi...
متن کاملTerrasar X-band Insar Observations in Urban Areas
SAR (Synthetic Aperture Radar) has ability to detect subtle surface movement at the scale of millimeter to centimeter. TerraSAR-X is new radar satellite operated at X-band, multi polarization, and multi beam mode. Compared with C-band or L-band SAR, the X-band system inherently suffers from more temporal decorrelation due to short wavelength (3.1 cm), but is more sensitive to surface deformatio...
متن کاملUsing Terrasar-x and Rapideye Data for Change Detection in Wadden Sea Areas
The tidal areas of the oceans are important transition zones between terrestrial and marine ecosystems. In contrast to the non-marine surface of the earth, access to the tidal lands such as the Wadden Sea along the North Sea coast is often difficult. For this reason, remote sensing offers important monitoring tools. In this study, a new change detection approach is presented, adapted to the Wad...
متن کاملUrban monitoring and change detection of central Tokyo using TerraSAR - X images
Monitoring urban growth and change is an important issue for urban planning and disaster management. In this study, two different approaches are conducted to monitor the urban areas. One is that a TerraSAR-X image is compared with an ALOS/PALSAR image to investigate the characteristics of urban land cover in different radar wavelengths. Also, a very high resolution optical QuickBird image is us...
