The airborne multichannel scanners at present in use in the University of Michigan's flying program will be described. This equipment provided eighteen parallel outputs from eighteen detectors each operating at fixed optical bandwidths distributed over the .35 to 13.5 micron region. The pattern recognition concepts used to create compositional maps on the basis of the information carried in the parallel channels will be described as will the electronic equipment used to implement these concepts. Examples of the parallel stripmaps obtained will be shown as will examples of compositional maps generated with the equipment described. The extension and applicability of these techniques to future airborne and orbital remote sensing programs will be discussed.
