This paper presents a new method for unsupervised urban area extraction from SAR imagery. The image segmentation method combines variogram texture feature extraction with OTSU threshold segmentation method, to obtain the result as good as traditional classical algorithm and have much higher computational efficiency. TerraSAR-X image is used to validate the proposed method, and experimental resu...

The objective of this study is to investigate the potential of TerraSAR-X (X-band) in monitoring sugarcane growth on Reunion Island (located in the Indian Ocean). Multi-temporal TerraSAR data acquired at various incidence angles (17°, 31°, 37°, 47°, 58°) and polarizations (HH, HV, VV) were analyzed in order to study the behaviour of SAR (synthetic aperture radar) signal as a function of sugarca...

The first German space mission TerraSAR-X was launched on June 15th, 2007. Within the TerraSAR-X science program of the German Aerospace Center (DLR), the Institute of Digital Image Processing of Joanneum Research (JRDIB) has gained a principal investigator status with respect to the assessment of the mapping potential of TerraSAR-X data using radargrammetric as well as interferometric techniqu...

TerraSAR-X is a new German radar satellite that shall be launched in mid 2006. The expected lifetime is 5 years. It carries a high frequency X-band Synthetic Aperture Radar (SAR) sensor that can be operated in different modes and polarisation. The Spotlight-, Stripmapand ScanSAR-modes provide high resolution SAR images for detailed analysis as well as wide swath data whenever a larger coverage ...

This paper gives an overview of capabilities of TerraSAR-X and provides some first application results. The TerraSAR-X mission is based on a public-private-partnership agreement between the German Aerospace Centre DLR and EADS Astrium GmbH. It is the continuation of the scientifically and technologically successful radar missions X-SAR (1994) and SRTM (2000) and is designed for scientific and c...

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...

An L-band InSAR mission, EVINSAR, was proposed to ESA’s Earth Explorer Opportunity Mission programme in 2002 that would measure the strain cycles associated with earthquakes/tectonism and volcanoes. Although not funded the concept was encouraged by ESA and the EVINSAR Science Team was asked to study how the science requirements of EVINSAR could be met by the proposed TerraSAR-L mission. The EVI...

TerraSAR-X, the first national German radar satellite, is scheduled for launch in 2006. It carries an X-band highresolution synthetic aperture radar instrument featuring imaging modes like StripMap, ScanSAR and, particularly, SpotLight in a variety of different polarization modes [1] [2]. Thus the TerraSAR-X mission will provide both the scientific [3] and commercial [4] user community with a v...

In the past few years, the Himalayan region has experienced a number of floods from glacial lakes, and the neighboring areas were severely damaged. Therefore it is important to continue monitoring glaciers or creating simulation of floods to prevent the damages in those regions. The DEM is very useful for studying these hazardous problems. In this study, we tried to generate DEM by TerraSAR-X i...
