AbstractThe environmental impact of mine tailings is a nation-wide problem in Canada. Mine tailings affect the environment primarily through acid mine drainage (AMD). AMD contains toxic concentrations of metals and dissolved salts which can contaminate ground and surface water. There is a clear need for monitoring mine-tailing sites in order to ensure that damage to the environment is kept to a minimum. The availability of high spatial resolution hyperspectral airborne imagery, acquired by sensors such as the Compact Airborne Spectrographic Imager (casi), has greatly improved the potential for automated mapping of mine tailings. In this paper, we investigate the potential of casi data for use in AMD detection. Both constrained and unconstrained linear spectral unmixing was performed on summer 1998 casi data acquired over the Copper Cliff tailings area in Ontario, Canada. Preliminary results show that spectral unmixing of casi data can provide valuable information on the occurrence of AMD.
