Zusammenfassung
Remote sensing is an integral part of mineral exploration and mine waste monitoring today. The pool of geoscientific applications for remote sensing is rapidly growing with the advent of new spaceborne sensors such as the hyperspectral EnMAP (Environmental Mapping and Analysis Program) and the multispectral Sentinel-2 missions. The main advantage of hyperspectral data is the capability to identify surface materials via their characteristic absorption features, casually called “the spectral fingerprint” and map their spatial distribution. These characteristic absorption features can be used e.g. to map the abundance of rare earth elements, or map mineral assemblages that are characteristic for sulfide ore deposits. In addition to that, mine waste material can be characterized and mapped. South Africa and Namibia with their long mining history provide excellent natural laboratories for the development of new geoscientific applications for mineral exploration and environmental monitoring, due to the large areas affected by tailings dams and the large and remote desert areas, which hold the potential for new mineral deposit sites. Hyperspectral airborne data is widely used in South Africa and Namibia. However, it is too sparse and too expensive for certain applications such as the environmental monitoring of tailings sites. A combination of multispectral and hyperspectral spaceborne sensors has shown its potential to bridge this apparent gap in mine waste mapping and monitoring.
