This document analyzes trends in ground deformation measured by permanent scatterer interferometry (PSInSAR) in mining areas in Poland's Dabrowski Coal Basin. PSInSAR identified 6,105 measurement points and detected trend changes in ground deformation over time periods between 1992-2003. For 41% of points, deformation trends changed during six time periods. The analysis also examined the "Grodziec" coal mine individually, finding trend changes for 45.3% of its 535 measurement points, most frequently involving increases or decreases in subsidence rates. Spatial maps of measurement point density showed where trend changes occurred within mining areas.
