Profile tracer

from Wikipedia, the free encyclopedia

The Profile Tracer was an instrument that was moved through the site on a two-wheeled handcart and with which the topography of a site was automatically recorded on a rotating drum. This should make the previously customary teams of surveyors superfluous.

The device was developed in 1913 by Vannevar Bush , then still a student at Tufts University . The Profile Tracer was registered as a patent in the United States Patent Office on February 2, 1912 under publication number US1048649 A. Vannevar Bush is registered as the inventor.
