The Advanced Along-Track Scanning Radiometer (AATSR), launched on ENVISAT in March 2002, is the third in a series of instrument designed to make precise and accurate global Sea Surface Temperature (SST) estimations. At the time of the ENVISAT Symposium 2007, geophysical validation indicates that the AATSR 1 km and 10' spatially averaged D3 SSTs are generally in specification, in that AATSR 1 km...

The main objective of this project is to develop and test methodology using ENVISAT ASAR data for agricultural applications, with an emphasis on land use, land cover classification and rice mapping. An optimal pre-processing chain for ASAR data is first constructed to provide input data to the classification steps. Experiments at the Zhangzhou test site, Fujian province, southern China, indicat...

The aim of this research is to investigate the terrain deformation in the metropolitan area of Sydney using multiple satellite radar imagery. The persistent scatterer interferometry (PSI) strategy developed at Geodesy and Earth Observing Systems Group (GEOS) of the University of New South Wales (UNSW) is used to map the land deformation in Sydney with C-band ENVISAT radar images in this study. ...

Near-real time altimetry products from ENVISAT RA2, Jason 1 and Topex/Poseidon tandem mission are validated for the North Sea and Baltic Sea region to assess the feasibility of using the data for operational purposes. The coverage of the satellite data shows that all Jason 1 and Topex/Poseidon observations in the Baltic Sea are currently discarded in the processing of the data. The spatial scal...

We present a framework for automatic detection of oil spills in SAR images. Multi incident angle and multi polarization SAR data are ingested into the framework in order to optimize revisit times and thereby the temporal and spatial coverage. Dark spots in the images are primarily detected by adaptive thresholding. For each of them a number of features are computed in order to classify the slic...

This paper presents the I.D.I.O.T. (InSAR Deformation Inspection and Observation Tool) software, developed by the Computer Vision and Remote Sensing Group of the Berlin University of Technology. The purpose of I.D.I.O.T. is to ease as much as possible the generation of differential SAR interferograms, even for complete novices in SAR interferometry. The generation of differential interferograms...

Water levels and water extents are essential information in flood monitoring and forecasting. Two experimental and complementary ways were explored in order to estimate water level and water extent and forecast them: 1) The estimation of water level through combining water extents derived from earth observation data with elevation from a Digital Elevation Model; 2) The estimation of flood exten...

Soil moisture is a key variable for the water and energy exchanges at the land surface. The determination of soil moisture dynamics from space is one of the most prominent, but also most challenging applications for recent active microwave sensor systems. Since the launch of ENVISAT ASAR, more than 4 years of data is available for the retrieval of soil moisture information. The wide area covera...

RESUME Wide swath imagery of the ENVISAT Advanced Synthetic Aperture Radar (ASAR) may be used to study and map biophysical parameters of the Siberian forest. Within this study multi incidence-angle capacities of the ASAR Wide Swath (WS) mode for deriving forest types and biomass parameters are assessed. For this purpose a processing chain was set up to manage orthorectify, calibrate and analyse...

In this article a method based on data fusion approach and using multitemporal ASAR-ENVISAT / PRI-ERS SAR images to analyze different behaviours (urban growth, urban decrease and urban constance) of the urban dynamics phenomenon in rain forest context is proposed. The method computes first two attributes : NDVI index used as urban / non-urban index and as prior information to improve locally th...
