DEM Reconstruction of Coastal Geomorphology from DINSAR
The paper is focused on Digital Elevation Model (DEM) reconstruction from differential interferometry synthetic aperture radar (DInSAR). In doing so, conventional DInSAR procedures are implemented to three repeat passes of RADARSAT-1 SAR fine mode data (F1). Further, the multichannel MAP height estimator is implemented with phase unwrapping technique. Consequently, the multichannel MAP height e...
متن کاملMultichannel Map Height Estimator Algorithm for Dem Reconstruction from Dinsar
Interferometric synthetic aperture radar (InSAR or IfSAR), is a geodetic technique uses two or more single look complex synthetic aperture radar (SAR) images to produce maps of surface deformation or digital elevation. It has applications as well, for monitoring of geophysical natural hazards, for instance earthquakes, volcanoes and landslides, also in engineering, in particular recording of su...
متن کاملERS-ENVISAT Cross-interferometry for Coastal DEM Construction
Digital elevation models (DEMs) of a coastal area in a time series are very useful to monitor annual and seasonal coastal morphologic changes. Topographic features in coastal regions change significantly within a relatively short period compared with landmass. However, it is difficult to obtain coherent interferometric SAR pairs over coastal areas. ERS-ENVISAT 30-minute tandem pair is useful to...
متن کاملA method of DEM construction and related error analysis
The concept and the computation of terrain representation error (ETR) are investigated and total DEM error is presented as an accuracy index for DEM evaluation at a global level. A promising method of surface modelling based on the theorem of surfaces (SMTS) has been developed. A numerical test and a real-world example are employed to comparatively analyze the simulation accuracy of SMTS and th...
