| Abstract: | Altered rock is a kind of rock unit in metallogenic belt,which has specially spatial structure and mineral component.In remote sensing image,the spatial structure forms spatial recognizing information,the mineral component forms spectral recognizing information.This paper respectively discusses the image detection methods based on alteration rock spatial structure,and the spectral information recognition methods based on the feature spectra of altered rock.The methods such as the best spectral combination and spectral ratio and multispectral bands analysis are described with emphasis in the paper,and the basic working procedure in making remote sensing map of altered rock is introduced too. |
