AbstractHyperspectral imagery from the Compact Airborne Spectrographic Imager (casi) was used to monitor sulphide mine tailings revegetation progress at the Copper Cliff mine in Sudbury, Ontario. A first set of data was acquired on August 24, 1996 in 72 contiguous 9 nm wide spectral bands from 400 nm to 950 nm along with a detailed ground survey. Using the same image acquisition parameters, a second set of data was acquired on August 19, 1998 over the same area along with detailed ground reference measurements. Both sets of image data were classified using constrained linear spectral unmixing. Monitoring was achieved by comparing the 1996 and 1998 image fractions of vegetation. Results indicate that advances in reclamation of the selected sites have been made over the two-year period.
