Claim One:
1. Apparatus for producing color classification maps from multispectral scanner data in which the color classification of the multispectral data can be changed in real-time, comprising: a source of a plurality of channels of multispectral data in digital format representative of the reflectance of preselected ground resolution elements, transform means for receiving said plurality of channels of multispectral data in digital format and providing a like plurality of analog voltage output signals, a selected instantaneous voltage of each of said signals being representative of a selected spectral signature functionally related to said reflectance of one of said ground resolution elements, processor means responsive to said plurality of analog voltage output signals for developing primary color classification signals functionally related to said spectral signatures, said processor means including interactive control means for changing said primary color classification signals to effect a change in the color classification of the visually displayed multispectral data, and display means responsive to said primary color classification signals for producing a visual display in map form of said multispectral data.
