Method of and apparatus for registering a single dimensional image to a two dimensional image, and for generating spectral two dimensional images, as practiced in aerial imagery. Raw data or primary images are acquired from a subject of interest and are passed through a camera type aperture and divided by passing the light beam through a beam splitter. One beam is recorded digitally as two dimensional images containing at least three recognizable geometric reference points. The second beam is passed through a slit to form single dimensional images, which are then preferably diffracted to produce plural spectral single dimensional images. The spectral single dimensional images are recorded digitally in a manner enabling each single dimensional image to be linked to its corresponding two dimensional reference image. The beam splitter and slit device may be replaced by a selectively reflective beam splitter which accomplishes the function of both deleted components. Spectral two dimensional images may be reconstituted from the single dimensional digital record by manipulating the data to position each single dimensional image appropriately within an array. Proper location of each single dimensional image is accomplished by positioning it according to its relation to the geometric reference points. Thus a plurality of two dimensional images, each corresponding to one band of the spectrum, can be reconstituted for each original reference image.
