| Description
| - We concentrate on areas with abandoned open brown coal mines, or undermined areas. We made analyzes of terrain deformation in the area of the Slatinice above-level dump that is monitored because of potential terrain deformations. The 2-pass differential interferometry method was used. Interferometric processing was performed in the GAMMA software. The differential interferogram for the 2-pass method was filtered and then unwrapped. Due to filtering we achieved much better coherence. Unwrapped phase of that differential interferogram can be used for a terrain-deformation detection more profitably. An important feature of this method is that all measurements are relative. Theoretically, the phase of the differential interferogram should be zero in the areas of no deformation, but there are systematic errors influencing the measurements and therefore the deformations can be determined only relatively with respect to the vicinity. Expected deformations can be described quantitatively. For decision on potential terrain deformation, the suspect areas of subsidence must be sufficiently coherent. For incoherent areas there occurs decorrelation and thus loss of data. For subsidence confirmation, we demand as continuous phase as possible with a sufficient number of neighboring pixels and lines. Further we concentrated on the Jirkov-Most route and railway that slides and is also monitoring and leveled very precisely. Especially its part called the Ervenice corridor. We cannot evidence that area of the Ervenice corridor is stable because of larger variance of the unwrapped-phase values. The results are very decorrelated. In this area, we verified no terrain deformation.
