Abstract :
In this paper, SAR interferometry with JERS SAR data and ERS SAR data was applied to investigate the land subsidence evolvement tendency in Wuan, China from 1993 to 1998. The subsidence was caused not only by coal mining but also by iron mining, and the investigated region is covered with some vegetation. The investigation shows that in a plain area, as long as the image pairs´ time interval is short even if the perpendicular baseline exceeds 1100 m, it is possible to obtain a good interferometry effect with JERS SAR data.
