|Abstract||The deleterious effect of environmental pollution is a major international problem. Developing cost-effective techniques to monitor, clean up and restore these polluted areas are also of major concern.
In North America alone, over 100000 abandon mining sites, containing hazardous wastes, need to be restored.|
Several operational geomatic techniques are now being used for mapping polluted areas and for monitoring the clean up and restoration
activities. These techniques are also constantly being revised with the availability of higher spatial and spectral resolutions of new remote sensing systems. In this paper, we provide examples using airborne and satellite multispectral images to
monitor restoration activities at mining sites, as well as mapping features for groundwater protection.
