ABSTRACT 
Several remote sensing and GIS techniques have been developed in recent years for characterizing areas 
of acid mine drainage. This paper will provide a review of the current remote sensing techniques that 
have been used to detect and monitor acid mine drainage, and present case studies on the use of field and 
airborne spectral techniques. From these examples the field spectral techniques have been used not only 
as a process of detecting the geochemical effects on the surrounding vegetation, but serves as a guide to 
image processing of high resolution airborne multispectral images. Our results have also shown that 
although multispectral satellite images can be used to delineate mining activities; site characterization of 
acid mine drainage sites do require high resolution airborne and field techniques.
