In recent years, space-borne InSAR (interferometric synthetic aperture radar) techniques havernshown their capabilities to provide precise measurements of Earth surface displacements forrnmonitoring urban infrastructure. The methodology described in this paper aims at detecting groundrnmotions and structural deformations at the whole city and local scale, In this research, present tworntest sites studies on how space geodetic tools, especially Radar Interferometry (InSAR), can be usedrnto monitor structural deformation. First, investigate the land subside and uplifting extent andrnseverity area of deformation in the city of Addis Ababa using InSAR. Short wavelength C-bandrndata are explored in this study. The integrated use of interferometric synthetic aperture radarrntechnology for monitoring structural deformation offers several perspectives for investigation ofrnnew and aging infrastructure around the city. Spanning almost 12 years space born of observation,rnand the interferograms produced from the raw ENVISAT and SENTENIEL data to performrnclassical PS-INSAR analysis in corporate measurement those satellite data. and can be detect a longrnterm maximum land subsidence rate of about -36.78mm/yr measuring at PSINSAR , and minimumrn3mm of uplifting are detected. The quantitative validation results of the InSAR-derived deformationrntrend during the five observation periods are stable with the ADIS GPS station data measured fromrn2014 to 2018. Overall, the adopted methodology can be used successfully for detection, mappingrnand monitoring of the subsiding areas vulnerable to future collapse. This will facilitate efficientrnplanning and designing of surface infrastructures and other developmental structures in the urbanrnareas and mitigation management of subsidence induced hazards.
