Description
  • V Sokolovské pánvi byly aplikovány metody spektroradiometrie zaměřené na analýzu superspektrálních satelitních dat ASTER v kombinaci s pozemní spektroradiometrií (ASD Filedspec spectroradiometer) za účelem testování možností a potenciálu využití těchto metod pro identifikaci zdrojových center vznikající acidifikace (AMD). Data z pozemních měření ASD spektrometrem spolu s laboratorními spektroradiometrickými měřeními provedenými stejným přístrojem provedenými nad typovými mineralogickými a horninovými vzorky sokolovské pánve byly využity jak pro vlastní kalibraci satelitních dat, tak i pro jejich minerální klasifikaci.Hlavní důraz byl kladen na testování různých klasifikačních algoritmů od jednoduchých, které berou v úvahu pouze jednosložkový obsah pixelu (SAM – Spectral Angle Mapper) přes složitější algoritmy zohledňující vícesložkový (směsný) obsah pixelu (Spectral Unmixing) a klasifikující skupiny minerálů jakými jsou sulfáty, oxidy a oxi-hydroxidy kovů.

  • This paper present a preliminary study that aims at identifying locations of significant sources of Acid Mine Drainage at the Sokolov open pit, using space borne and ground-based spectroradiometry. The basin, dating from the Oligocene to Miocene epochs, extends over 8 to 9 km in width and 36 km long. Lignite is found only in the western part of the basin and comprises three exploited coal seams. ASTER satellite data together with ground-based spectroscopy were applied in order to assess their capabilities in identifying locations of the most significant sources of AMD discharge at the open-pit mine sites. First results comparing the mineral maps derived from ASTER imagery with field investigations, confirmed with XRD analyses, demonstrated the ability of spectral remote sensing in mapping mineral species such as secondary iron minerals. Image processing identified jarosite as a part of the mixture material in accordance with conducted XRD analyses.
