Elevation measurements of the continental water surface have been poorly collected with in situ measurements or occasionally with conventional altimeters with low accuracy. Techniques using InSAR at n...
This paper proposes a science and technology education program to teach junior high school students to measure terrain changes by using interferometric synthetic aperture radar (SAR). The objectives o...
Digital elevation models (DEM) from satellite data are generated mainly from two types of datasets using completely different methods: photogrammetry for optical stereo images (e.g. SPOT5, CARTOSAT)...
Digital elevation models (DEM) from satellite data are generated mainly from two types of datasets using completely different methods: photogrammetry for optical stereo images (e.g. SPOT5, IKONOS) and...
Leberl (Leberl, 1990) proposed an edge-based algorithm for finding matching pairs of points in SAR images. In this paper, we show that the algorithm can be used to register interferometric SAR images ...
D-InSAR data of ground surface deformation have uncertainty caused by several sources associated with image acquisitions and data processing. In this study, these data are modeled as the sum of a tren...
The paper focuses on the differential interferometric SAR (Synthetic Aperture Radar) technique for the monitoring of terrain surface deformations. The paper begins with a concise description of the pr...
Automatic extraction of built-up areas from a multitemporal interferometric ERS-1/2 Tandem SAR dataset was studied. The image data were segmented into homogeneous regions and the regions were classi...
Requirements for precise digital elevation data (i.e., Digital Elevation Models, or DEMs) of varying levels of detail are being formulated for different fields of application. The degree of detail fou...
A new interferometric SAR (InSAR) procedure for DEM generation was employed to generate different DEMs from ERS SAR image pairs. The procedure was validated comparing the InSAR DEMs with a suited refe...
The improved quality of InSAR data suggests to utilise such data for building detection. But, the phase information from which the height data is calculated, is often severely disturbed, depending on ...
Land subsidence caused by withdrawal of groundwater has become one of the most serious hazards in many parts of the world, particularly in densely populated and economically developed coastal areas. L...
Within the past few years there has been a significant increase in the use of Digital Elevation Models (DEMs), for applications as varied as telecommunications and precision agriculture, forestry and ...
The accuracy of system parameters is one of the key factors that limit the precision of DEM from airborne dual-antenna InSAR, so the interferometric calibration is of great significance. The traditi...
Along-track interferometric synthetic aperture radar (AT-InSAR) systems are used to estimate the radial velocity of targets moving on the ground, starting from the interferometric phases, obtained by ...
