Universal map display system specially adapted for pictorial representation of an optionally referenced object on a corresponding map background

摘要

The field of the invention is that of the displaying on a map background with substantially flat surface, in particular being viewed on a cathode screen, of arbitrarily referenced objects (UTM or geographical coordinates) on the Earth's surface. The aim is to provide a completely universal map display system which can be installed on an automated machine. This aim is achieved with the aid of a system characterised in that it comprises: . means (44) of storing map backgrounds, . means (42, 43) of assigning a universal reference to each of the said referenced objects; . means (45) of initialising displaying of the said points superimposed on an appropriate map background; . means (46) of converting the said universal reference of each of the said points into Cartesian coordinates characteristic of the said appropriate viewing map background.
