利用金矿围岩怕变的光谱特征,作不同波段的比值图象,增强围岩蚀变信息。再将这些增强了的信息集中起来,使金矿信息明显化,达到从遥感资料直接找矿的目的。
The ratio images were made to enhance the information of wallrock alteration by utilizing the spectral characteristics of wall rock alteration of gold deposits. The ratio images were Composed to concentrate the information of wall rock alteration which has been enhanced and make the gold deposits information to be obvious in order to survey the gold deposit from remote sensing data directly.
