This contribution reports on the potential of L-band Permanent Scatterer technique for the detection and monitoring of ground subsidence. We present the use of PS in the abandoned mining area, Korea. Discrete and temporarily stable natural reflectors or permanent scatterers (PS) can be identified from long temporal series of interferometric SAR images. This subset of image pixels can be exploited successfully for high accuracy differential measurements (Ferretti et al., 2000).
