A cartographic indicator, usable aboard an aircraft, comprises an analyzer continuously scanning a recording medium such as an optical film or a magnetic tape on which sections of a multicolor map are stored with a reduced spectral range, i.e. as a limited number of intensities possibly allocated to two different color components. The signals or pairs of signals emitted by the analyzer upon point-by-point scanning of the recording medium are fed to a transcoder, including a programmable read-only memory, which converts them into respective combinations of three signal components respectively representing the basic colors red, green and blue; the relative magnitudes of these signal components determine the contributions of the corresponding basic colors to an image point visualized by a multicolor display device.
