Abstract
Abstract A cartographic means and method employs two or more compound microscopes having optical paths combined through semireflective means. One of the microscopes has means for receiving an input record in its object plane while the other has an output record in a horizontal object plane beneath its objective. Image modification means including a zoom system and preferably an image rotation mechanism and an anamorphic system are included in the input microscope system to permit the input image to be matched to the output image as both are viewed through the eyepieces. Various apparatus and methods for mounting, illuminating and scanning inputs, handling outputs, supporting the instrument, photographing the superimposed images and transferring data from input to output are described.
