A DEVICE FOR SEMIAUTOMATIC PLOTTING OF THE PROFILE OF THE EARTH'S SURFACE FROM TOPOGRAPHIC CHARTS,
Abstract
The Author introduces a device for semiautomatically charting a profile of the earth's surface from topographic maps. The instrument contains a mechanical profilograph, a unit for monitoring and control, and units for extraction of information. To simplify the design and to obtain information on the local terrain in digital form, machine code, or as a graph, the profilograph is made in the form of a curvometer mechanism with a roller which is connected through gearing to an electrically coding disc. Brushes contacting the disc are used to convert linear motion to electrical pulses which are then counted by reversible counters with the results being transmitted to the information extraction unit.
