Usage of InSAR techniques to detect and monitor terrain subsidence due to the mining activities

Popis výsledku v původním jazyce

In the area of Northern Moravia several active mines are located causing subsidence even 1m a year. Existing radar images from ERS-1, ERS-2 and Envisat satellites of 1996-2008, were processed by 2-pass differential radar interferometry and advanced methods of radar interferometry, subsidence epicentres were indicated and subsidence rates estimated. The evolution and movement of subsidence can be observed, however, when compared to the survey data it is apparent that the predicted subsidence rate is heavily underestimated. This is due to sensitivity of the radar interferometry method to the quality of input data - only a very small number from 128 available images could be properly combined. The subsiding area was detected in the period 1996-2000, but no correct data on the rate of subsidence is available.
