Utilization of spectroradiometric measurements for identification of acid weathered substrates – Case studyfrom the Sokolov basin
Abstract
Mineral spectroradiometry, using both airborne or spaceborne sensors and ground measurements, represents an alternative to conventional methods and efficient way to characterize mining sites together with the surrounding environment and assess the potential for mapping acid "hot spots". High-altitude spectroradiometry (ASTER - Advanced Spaceborne Thermal Emission and Reflection Radiometer satellite data) together with ground-based spectroradiometry (ASD Filedspec 3® spectroradiometer) were applied in order to define the capability for identifying the locations of the most significant sources of acidification at the Sokolov open-pit mine site. First results comparing the maps derived from ASTER imagery with the field investigations demonstrated the ability of spectral remote sensing to map such mineral species as secondary iron minerals and organic component (e.g. humic acid) as well.
