Earth Observation satellites acquire huge volumes of high resolution images continuously increasing the size of the archives and the variety of EO products. However, only a small part of this data is exploited. In this paper, we present how we take advantage of the TerraSAR-X images of the German Aerospace Center in order to build applications on top of EO data.

The aim of this study was to develop an inversion approach to estimate surface soil 19 moisture from X-band SAR data over irrigated grassland areas. This approach simulates a 20 coupling scenario between Synthetic Aperture Radar (SAR) and optical images through the 21 Water Cloud Model (WCM). A time series of SAR (TerraSAR-X and COSMO-SkyMed) and 22

The results of an interferometric performance analysis for spaceborne parasitic SAR configurations are presented. The analysis includes errors due to limited SNR, block adaptive quantization, range and azimuth ambiguities, and geometric decorrelation for both flat surfaces and random volumes. Relative height accuracies for three spaceborne configurations with PALSAR, ASAR and TerraSAR-X as illu...

The topic of this paper is the definition of a geometric model for stereo pair orientation of SpotLight Synthetic Aperture Radar (SAR) imagery collected by the new high amplitude resolution radar sensors COSMO-SkyMed (Italian) and TerraSAR-X (German). The suite for radargrammetric approach has been implemented in SISAR (Software per Immagini Satellitari ad Alta Risoluzione), a scientific softwa...

In the last year, the TerraSAR-X sensor began to provide a great amount of data, thus increasing the possibility to extract valuable information from SAR images. Indeed, these high resolution images are increasingly more textured and present many details previously masked due to the low resolution of the available sensors. This certainly represents an advance for remote sensing applications, bu...

The German remote sensing satellite TerraSAR-X, launched in 2007, hosts a flexible XBand synthetic aperture radar (SAR) operating in Stripmap, Spotlight, ScanSAR, and additional experimental modes. For these various antenna beams, its active phased array antenna electronically steers and shapes the patterns in azimuth and elevation direction. The array consists of 384 radiating sub-arrays for h...

High precision DEM of a tidal-flat is valuable to coastal management as well as pure scientific interest including erosion and sedimentation rate study. Geomorphologic mapping in coastal zone is, however, complicated by the rapid and significant changes on many fluvial forms and poor topographic expression of the landform. Three space-borne SAR systems including ALOS PALSAR, TerrrSAR-X and ERS-...

Clay content (fraction < 2 μm) is one of the most important soil properties. It controls soil hydraulic properties like wilting point, field capacity and saturated hydraulic conductivity, which in turn control the various fluxes of water in the unsaturated zone. In our study site, the Kairouan plain in central Tunisia, existing soil maps are neither exhaustive nor sufficiently precise for water...

The SAR (Synthetic Aperture Radar) imagery are largely used for the environmental, structures and infrastructures monitoring. In particular, Differential SAR Interferometry (DInSAR) is a well known technique that allows producing spatially dense displacement maps with centimetre to millimetre accuracy. The SAR signal is characterized by phase and amplitude value and the DInSAR remote sensing te...
