SummaryThe proposed project deals with the acquisition and observation of vertical displacements in Berezniki, a city in the region Perm in Russia. Under the city a potash mine has been closed because of a mine accident with an uncontrollable water inrush. Caused by the water inrush a sink hole already occurred on the outskirts. For utilisation the results of Differential SAR Interferometry (DInSAR) and Interferometric Point Target Analysis (IPTA) will be used. Actually we monitor this area already with ENVISAT data. We aim for a comparison of these, about their resolution, wavelength and iteration rate, different data sets and want to find out the advantages and possible handicaps of TerraSAR-X for the monitoring of vertical displacements.
In addition to the StripMap data, SpotLight mode data shall be analysed. On the one hand it is intended to gain experience with the new data with its higher resolution. On the other hand the possibility of increasing the accuracy, the quality and the reliability shall be investigated for both DInSAR and IPTA analyses in comparison to StripMap data.
The project is funded by the Mining Institute of the Russian Academy of Science, Perm.
