From approximately tomore t minute maps were made to cover the 48 conterminous states. Producing an accurate topographic map is a long and complex process. It can take 5 years from the identification of a mapping requirement to the printing of a large-scale map like one of the USGS minute, ,scale quadrangle maps.
the mapping process, and USGS employees were quick to embrace this technology. In the s, USGS developed the AutoPlot, a device that used stepping motors to move scribing engravers to create a scribe coat negative of the topographic map neat line (latitude and longitude lines that bound the quadrangles) and horizontal pass points.
