Abstract
Visualizable and descriptive data handling system including an assembly comprising a unit for reading a video disk on which images of schematic detailed layouts that can be displayed on a unit screen are recorded. A double entry table, T.sub.xy in memory correlates each of the image divisions of coordinates x.sub.i Y.sub.i with a memory location which itself contains the memory location address from which the descriptive data relative to the image element occupying the square, are stored. For every image, a table T.sub.REF of descriptive data is built through data input means, the memory address, where begin each of the descriptive data for a given image element, being recorded in table T.sub.xy at the address correlated with x.sub.i y.sub.j. When pointing a light pen on to the screen, the coordinates of the selected point are sent from a mini-computer which causes the descriptive data corresponding to the selected element, to be displayed upon look-up of the tables corresponding to the display image.
