Digital elevation model generation from satellite interferometric synthetic aperture radar
An accurate digital elevation model (DEM) is a critical data set for characterizing the natural landscape, monitoring natural hazards, and georeferencing satellite imagery. The ideal interferometric synthetic aperture radar (InSAR) configuration for DEM production is a single-pass two-antenna system. Repeat-pass single-antenna satellite InSAR imagery, however, also can be used to produce useful...
متن کاملDigital Elevation Model Generation from Interferometric Synthetic Aperture Radar Using Multi-scale Method
Digital Elevation Models (DEMs) can be generated using a variety of techniques and data sources including levelling, photogrammetry, SAR interferometry, radargrammetry, and laser scanning. These different-sourced DEMs are affected by different systematic vertical and horizontal errors, as well as random noise. Moreover, each DEM generally has different spatial resolution and coverage. In genera...
متن کاملInterferometric Synthetic Aperture Radar
This paper provides a brief review of interferometric synthetic aperture radar (InSAR), its history, the theory, and design / implementation / processing issues. Along-track, single-pass and repeat-pass cross-track interferometry are reviewed. Specific topics addressed include error sources and phase-unwrapping techniques. Several examples of InSAR applications are presented. Introduction For y...
متن کاملCalibration of interferometric synthetic aperture radar digital elevation models (DEM) using error surface interpolation methods
Digital elevation models (DEM) are numerical representation of terrain elevation data that has been used in a wide range of spatial analysis applications. The principles for acquisition, storage, management, update, spatial analysis, visualization as well as integration with other systems are reasonably well known. However, as DEM applications are becoming increasingly more widespread, so does ...
متن کاملInterferometric synthetic-aperture radar (InSAR)
Geodesists are, for the most part, a patient and hardworking lot. A day spent hiking to a distant peak, hours spent waiting for clouds to clear a lineof-sight between observation points, weeks spent moving methodically along a level line – such is the normal pulse of the geodetic profession. The fruits of such labors are all the more precious because they are so scarce. A good day spent with an...
