Map making used to be an arduous, time-consuming, and often dangerous process. Although modern map-making is often still an arduous, time-consuming, and in some instances, dangerous process, new technologies are continually invented that make it easier. Modern Mechanix from July 1946 features a Coe-graph invented by Australian Lt. Col. H. J. F. Coe. It is a calibrated ground wheel attached to a paper roller and pencil. The design is still around in the form of digital rolling measurement wheels. It made me think of how technology and tools often remain the same, even when alternative technologies are available. A 2004 ESRI presentation by GeoSpatial Innovations compared the use of GPS versus measurement wheels for rural line design. A Civil Engineering Group posted a recent article on all of the methods for measuring area of land and a brief history of technology including GPS, measurement wheels, planimeters, and graph paper.
