The present paper describes an approach to the colour display of multispectral imagery. It is not restricted to ERTS data or to four-band imagery, but can be extended to airborne multi-band sensor systems. Rather than attempting to combine pictorially the information from the different bands, the information contained in the various bands is extracted in terms of several statistically uncorrelated images. These extracted images are then used as the basis of a colour display.
