[ABSTRACT]Subsidence in urban area has the potential to cause severe damage in ecosystem. Therefore it is important to understand the subsidence phenomenon in urban area. The objective of this study is to investigate the land deformation in the metropolitan area of Jakarta, Indonesia using multiple satellite radar imagery. Differential synthetic aperture radar interferometry (DInSAR) is a technique useful for accurately detecting the ground displacement or land deformation in the antenna line-of-sight (slant-range) direction using synthetic aperture radar (SAR) data taken at two separate acquisition times. In this study the DInSAR technique was used to map the land subsidence in Jakarta region with X-band TerraSAR radar images. A total of 4 TerraSAR-X images acquired from 9 August 2010 to 1 March 2013 over Jakarta were used in this study. The results demonstrated that the land in the area of Cengkareng was deforming at different rates. Several subsidence bowls with peak displacement rates 10 - 17.5 cm/yr along the radar looking direction have been observed Cengkareng.
