摘要
Rewarding results have been achieved in ore mineral exploration using multispectral data of satellite remote sensing.The ETM+ data are widely used because of the wide wavelength coverage,multi-band,low cost and so on.With ETM+ data,the authors were able to extract alteration remote sensing anomalies which are quite consistent with the field geological observations in the Heicigou area,during which iron staining and clayzation remote sensing anomalies were extracted respectively.Mask technology was utilized to eliminate the interferences of cloud,snow and ice,salinate fields,salt marsh,and vegetation.
