DSMs GENERATION FROM TERRASAR-X HIGH RESOLUTION SPOTLIGHT IMAGERY: EVALUATION OF RADARGRAMMETRIC APPROACHES IMPLEMENTED IN THE SCIENTIFIC SOFTWARE SISAR
One relevant application of SAR remote sensing is the generation of Digital Surface Models (DSMs) of the Earth's surface, thanks to the SAR independence from logistic constraints on the ground, illumination and weather conditions. Starting from SAR imagery two different approaches can be used to generate DSMs: the well known interferometric and the promising radargrammetric one. The goal of thi...

The availability of new high resolution radar spaceborne sensors offers new interesting potentialities for the geomatics application: spatial and temporal change detection, features extraction, generation of Digital Surface (DSMs). As regards the DSMs generation from new high resolution data (as SpotLight imagery), the development and the accuracy assessment of method based on radargrammetric a...
متن کاملA novel Radargrammetric Model and a RPCs Generation Strategy: Application with COSMO-SkyMed and Terra SAR-X Imagery
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...
متن کامل3D Mapping Potential of COSMO-SkyMed Sensor: Definition of an Image Matching Strategy
The topic of this paper is the presentation of an image matching technique suited to generate Digital Surface Models (DSMs) following a radargrammetric approach applied to SpotLight Synthetic Aperture Radar (SAR) stereo pairs collected by the new high amplitude resolution radar sensors COSMO-SkyMed (Italian) and TerraSAR-X (German). At present, thanks to this kind of imagery (GSD up to 1 m), th...
متن کاملEvaluation of Radargrammetry DEMs based on TerraSAR-X Staring SpotLight Imagery
For several years the technique of radargrammetry with high resolution Synthetic Aperture Radar (SAR) data has been used in scientific and commercial environment for Digital Elevation Modelling (DEM). Compared to repeat pass interferometry, radargrammetry is a robust DEM generation technique for almost all areas on the globe due to phase independent matching algorithms. Particularly in areas wi...
