AbstractWaste byproducts of mining activities can have environmental, social, and economic impacts. In some cases, resulting elevated concentrations of heavy metals and acid-generating tailings leave an environmental footprint that requires long-term monitoring of remediation efforts to prevent or reduce the degradation of surrounding ecosystems. In other examples, the presence of toxic, and sometimes radioactive, wastes can pose immediate health risks to nearby communities through dust dispersal and surface-water and groundwater contamination, and longer-term danger with contaminant transport throughout the regional environment. There are an estimated 27 000 orphaned and abandoned mines across Canada, and billions of dollars of remediation liability for acid-mine drainage, disruption of critical habitats, and related socio-economic impacts. Since 1991, legislation in Canada requires the mining industry to supply detailed procedures for the long-term management of mine-waste sites.
Information-extraction techniques exploiting Earth Observation and remote sensing data, in the form of software tools and processing methodologies, are discussed. The remote sensing data available for this study include airborne and satellite synthetic aperture radar (SAR) imagery, multispectral and broadband optical satellite imagery, and airborne and satellite hyperspectral imagery (imaging spectrometry), and in some cases multitemporal data sets are utilized. Several in situ data sets were collected to develop and validate the techniques. Sites discussed in this study include Seal Harbour, Nova Scotia; Britannia Beach, British Columbia; Key Lake, Saskatchewan; and Sudbury, Ontario.
