Proving Ancient Measurement Methods
Surveying students calculate the Earth’s circumference by following Eratosthene’s method, with help from modern sources. As part of the Geodetic and Control Surveys class at Dunwoody College of Technology in Minneapolis, Minnesota, we have been studying the history of Eratosthenes and how he calculated the circumference of the Earth. As a class we decided to...

Mapping the Appalachian Trail
How the AT was created and surveyed, from Avery’s wheel to GPS The Appalachian Trail (AT) is very old, very long, and iconic. Completed in 1937, it stretches 2,189 miles through 14 states, 88 counties, 168 townships, eight national forests, six national parks, two national wildlife refuges, and more than 65 state game lands, wildlife...
