PROBLEMATYKA WYKORZYSTANIA INTERFEROMETRII SATELITARNEJ W BADANIACH GEOLOGICZNYCH

Abstract

ISSUES CONCERNING THE APPLICATION OF SATELLITE INTERFEROMETRY IN GEOLOGICAL INVESTIGATIONSAbstract. The questions of the satellite interferometry method application for research studies of the geodynamics and ground movements in selected areas of Poland have been presented in this paper. The results of interferometric analysis from Upper Silesian Coal Basin (USCB) and Southern Baltic Coasts in the region of Gdańsk Bay were revealed. The advantages and limitations of the satellite interferometry for the ground movements studies have been also discussed. In the USCB area two interferometric methods were applied: PSI (based on the analysis of the data from satellites ERS-1 and ERS-2) and DifSAR (based on the analysis of the data from the Japanese satellite – ALOS). The results of interpretation have shown big utility for investigations of subsidence at the mining and post mining areas. On the basis of the PSI analysis of Southern Baltic Coasts several interesting phenomena have been observed. It was confi rmed that predominant part of Gdańsk-Gdynia-Sopot agglomeration is stable or nearly stable. One exception has been observed in the region of the Gdańsk Refi nery, where the subsidence rate of 12 mm/year was confi rmed. On the basis of the presented examples it could be concluded that the satellite interferometry is extremely useful for ground movement studies in the engineering-geological practice.
