摘要
The DEM containing topographic information, enhanced differential interferograms, corresponding coherence and maps of mining ground deformation are extracted by processing six ENVISAT ASAR data covering a mine of Jining by three-pass D-InSAR. Then, mine ground subsidence is analyzed in the light of distribution of mining subsidence and statistics of subsidence area. Finally, the accuracy analysis is executed by the way of comparing some level of monitoring result with the monitoring results from three-pass D-InSAR. The difference of the two monitoring results is shown,at the same time,main reason of it is discussed and analyzed preliminarily.
