Abstract
Since InSAR technique has a capability to detect a small surface elevation changes over large area, InSAR system has been used widely for good resolution mapping and other applications on various applied sciences. InSAR imagery is applied to investigate surface change and result detailed maps of contour, which help to detect disaster areas. This research is aimed to estimate the land subsidence using the differential interferometric synthetic aperture radar (InSAR). The research object is located in the west part of Japan, Kanto Plain area, where ground water actively is being extracted in quite large scale and produces centimeters of subsidence every year. Over the analyzed area, the surface deformation was detected and it was only related to subsidence process. In other words, there is no surface arising or uplift of surface. It signed by color phase changes correspond from zero to minus values.
