abstract = {Open-pit sulfide mining produces large quantities of waste rock that may contain materials
of economic interest. The exposure of sulfides accumulation may also pose a hazard to the
environment by causing phenomena such as acid mine drainage. This Master Thesis aims to
map and provide a geological characterization of the rock wastes of Corta Atalaya open pit in
Río Tinto, Spain. For this purpose, different hyperspectral imaging technologies that have
already demonstrated their effectiveness in mineral detection such as airborne remote sensing
in the VNIR and SWIR domain are used. This study is complemented with the incorporation
of an innovative hyperspectral method, the airborne LWIR. Our approach makes use of a set
of different spectral methods, and established image processing routines, such as band ratios,
and minimum wavelength maps. Supervised classifications are also employed as a mean to
extrapolate mapped rock types to larger unmapped areas, spectral angle maps, and to identify
high abundances of endmember lithologies, spectral unmixing techniques. Furthermore, this
study will lay the foundations and pave the way for possible future lines of research regarding
the Corta Atalaya rock wastes.},
