Multitemporal Analysis of the City of Nouakchott (Mauritania) Based on ENVISAT ASAR Images

Morphology of an arid landscape utilising synthetic-aperture radar (SAR) and differential interferometric SAR (DInSAR), southern Riyadh, Central Arabia

“…It is directly usable and comparable to the optical image, and is also directly related to the surface conditions, thus, some surfaces are represented by a high radiometric value, such as water surfaces, whereas dry surfaces appear with low radiometric values. SAR images have wide application in remote sensing and geological and environmental studies of arid and semi-arid lands (Troufleau et al, 1994;Singhroy and Saint-Jean, 1999;Wade et al, 2001;Hachemi et al, 2009;Hachemi and Thomas, 2013;Hachemi et al, 2014a, b;2015;. Differential interferometric synthetic-aperture radar (DInSAR) uses two or more SAR satellite images to generate maps of surface deformation or digital elevation, using differences in the phase of the waves returning to the satellite (e.g.…”

The diachronic analysis of island dynamics along the Vedea-Oltenița Danube river sector using SAR imagery

“…The radar amplitude images have been used in several fields and for different purposes. They have shown their usefulness and effectiveness in: the detection of soil surface moisture in arid and semi-arid zones (Troufleau et al 1994); monitoring deforestation, monitoring ice melt, lithology in the polar environment (Budkewitsch et al 1996a, b); the study and detection of mesoscale phenomena in oceanography (Laborde and Deveaux 1996); the pattern recognition, spatial planning (Rudant et al 1996); the classification of cultures (Bruniquel and Lopes 1994;Lopes and Sery 1997); mobility analysis and classification of Brakhanes dynamics (Hachemi and Thomas 2013;Hachemi et al 2020); the geological and structural mapping (Singhroy and Saint-Jean 1999;Wade et al 2001); the detection and characterization of oil spills in seas and oceans (Mercier et al 2004); the mapping of urban damage due to natural or industrial disasters and changes in coastal boundaries (Ba et al 2007); the flood extension mapping (Brivio et al 2002); mapping the evolution of the coastal features and the extension of cities (Hachemi et al 2014(Hachemi et al , 2015; the impact assessment and monitoring of the hydrological phenomena (floods, floods, etc.) in urban areas (Mcmillan et al 2006); the detection, analysis and interpretation of the landscape changes in very complex regions of the Carpathians (Hachemi et al 2009(Hachemi et al , 2010; the sedimentation mapping in shallow shoreline of the arid environments (Elhag and Bahrawi 2019); the flood inundation mapping and monitoring and its impact on Ramganga River in Ganga basin (Agnihotri et al 2019).…”
