FIELD: chart designing and making. SUBSTANCE: the device uses a contour detection and coding unit, contour image projection unit, coordinate code driver, code converter that drives the digit character signals via a counter and digit code signals, fed to the coordinate computer, and produces the coordinates of initial cartographic projection in the rectangular coordinate system by means of multiplier transformation matrices via the geodesic coordinates computer to the pattern register where they jointly with the image element visibility character are driven into signals of contour pattern digital model. All the above mentioned component are series-connected to the scanning unit. Signals from the pattern register are to the second input of the cartographic object register and, via the identifier computer, to its third input, whose first input receives signals from the contour detection and coding unit. The so formed digital model is compared in the storage unit with the known cartographic objects and then presented in the form of a cartographic image in the digital-chart model display unit. EFFECT: enhanced accuracy and capacity. |
