Abstract

The marble quarry, located in southern Austria produces high-quality marble, both in open-pit and underground extraction sites. Extraction, transportation and accumulation of material require close monitoring to maintain the stability of the whole area and to observe changes in waste dumps. In this study, we have shown how different methodologies can be used to support the monitoring of the entire raw material supply chain. Several unmanned aerial vehicle (UAV) surveys were performed to compute high-resolution digital elevation models (DEM) to serve as a reference for comparing stereo and tri-stereo DEMs calculated from satellite imagery. A low-cost global navigation satellite system (GNSS)-based monitoring system was set up to estimate horizontal and vertical displacements. In addition, the state-of-the-art technique of Interferometric synthetic aperture radar (InSAR) provided displacement time series for a broader area.
