A new technique for presenting satellite Landsat multispectral scanner (MSS) three-dimensional image data has been developed under a collaboration between the Canada Centre for Remote Sensing (CCRS) and the Polaroid Corporation. It consists of the production of white-light viewable holographic stereograms obtained by digital and optical processing of Landsat MSS stereo pairs. The digital processing extracts elevation information from suitable Landsat image pairs and synthesizes a sequence of fictitious perspective views. Laser optical processing is then used to merge these images into a white-light viewable holographic stereogram producing a black-and-white three-dimensional image of the earth's surface. The high quality of the relief image demonstrates the potential of computer/holographic hybrid techniques as tools for further analyses of remotely sensed data.
