Principal components analysis is already used in multispectral image analysis to reduce the number of spectral dimensions. We, propose to use projection pursuit to find interesting combinations of spectral variates that produce images that enhance, contrast differences between differing land-use types. We develop a 3-dimensional moment index based on Jones and Sibsons index for projection into 2-dimensions.
