A solid state scan converter is described that converts a family of profiles derived from photogrammetrically processed stereo imagery into a family of orthogonally projected contours for the purpose of display, editing, planning, and data processing. Transformations of the display of profiles such as rotation and scaling are discussed along with a stereo version of the system suitable as an on-line verification system in which orthogonally projected contours are superimposed upon the original stereo photos from which the profiles were derived.
