The study of method in monitoring mineral environment with remote sensing technology

Dexing Copper Mine, locating in the upper river of Dawu River and Le´an River in Jiangxi Province, is the largest copper mineral base in China. The development of the mine results in local environment degradation. This paper presents the method to monitor the local environment based on the remotely sensed images and field spectral data. Choosing remotely sensed images, TM data and ETM data in different time series, as well as field spectral data measured in October, 2002, the field spectral data are resampled in accordance with Gaussian Function. The vegetation spectral change around the mine is described with reflectance curve qualitatively, at the same time water pollution is shown quantificationally with Spectral Angel Mapping (SAM) method. The computed result fits with the ground truth very well.
