Abstract:For research purposes and the study area,the focus of this paper lies in two aspects:first,take the mask process-
ing,threshold-cutting,ratio of spectral bands,spectral angle mapper and prehensive analysis methods to remove the
noise information such as vegetation,shadows,rivers and water body disturbance of sediment,and so ,take the single-
window algorithm to invert the surface temperature using the ETM+ remote sensing image's thermal infrared spectral band.
Conduct the geological structure interpretation by inversion temperature overlay the abnormal alteration image data
with the g
