The results prove to be very satisfactory for the selection of optimal bands and lithologic interpretation of remote sensing pictures.展开更多
In the MSS waveband, rocks display no characteristic spectrum while the pattern of the Landsat images are important indications for interpretation. The pattern of an image is a composite of the shape, size, tone, etc....In the MSS waveband, rocks display no characteristic spectrum while the pattern of the Landsat images are important indications for interpretation. The pattern of an image is a composite of the shape, size, tone, etc. of surficial objects, while the pattern caused by rock is related with the predominant rock-forming minerals, litho-展开更多
