Abstract：2D scatter plot of remote sensing image,which is the best graphical representation method,expresses the structural information of the combination of two bands in spectral space; nevertheless, previous work only focused on such problems as the background - abnormal subspace model in the dot matrix space of spectral data,the estimation of the elliptical geometry parameters of 2D scatter plot based on the Gaussian distribution model of combination of 2 bands’ probability density,and the relationship between the background,interference and alteration anomaly of remote sensing image to the spatial structure of 2D scatter plot. Further studies show that the type classification of 2D scatter plot of remote sensing image is based on the physical meaning,and it can not only locate the background,interference and alteration information of the remote sensing image but also direct the selection of the method for the extraction of the remote sensing alteration information. At last,the authors discussed different kinds of 2D scatter plot practically used in the extraction of the remote sensing alteration information and,with practical examples, explained the theoretical basis and the application results of the 2D scatter plot used in the extraction of the remote sensing alteration information,which is based on the physical meaning.
