Moving map and other navigational display systems are disclosed herein which provide indications of relative position between a vehicle such as an aircraft and the terrain or other point(s) of reference. Optical images of a particular segment of terrain (or other reference data) are opto-mechanically selected in accordance with gross vehicle position; the selected segment image is coupled to a vidicon system or flying spot scanner system. By controlling the deflection circuits and thus the geometry of the vidicon raster or flying spot raster as a function of position and orientation of the vehicle as it moves, i.e. by electronically traversing the selected terrain image in duplication of the vehicle's motion (in accordance with the selected display stabilization mode), and photo-electrically sensing the image elements, a video representation of the vehicle's relative location and motion is obtained. This video is then displayed along with other desired data on a cathode ray tube or other display device.
