ABSTRACT:
Apparatus and a method are shown for automatically aligning a map with fi topographic and other features therein with an underlying display on which appear electronically produced symbols which must register with the map features. The misalignment of the map is automatically sensed and measured and the positions of all of the display symbols are shifted by an amount equal to the map's misalignment, so that the map and the display information are brought into proper registration.
