Abstract:

A new method of constructing isolines in accordance with an altitude matrix given within the nodes of a grid is proposed. The algorithm for this method was applied in a subsystem including an input device, a control digital computer, and an output device. If a Dnepr-1 computer is used, all the isolines on a map measuring 200 x 300 mm with a 0.2 mm stride can be plotted in about 3 hours, but the time can be shortened by several times if more highly advanced equipment is used.
