Robert Mills published the first known set of district (county) maps in an atlas of the state in 1825. Mills served as state architect for South Carolina, designing the State Lunatic Asylum and many local court houses, and later won the contest to design the Washington Monument in Washington, DC. Mills Atlas, made for the South Carolina State Legislature, contains 28 district maps and a state map, made from an earlier state sponsored survey of all the districts from 1817 to 1821, signed by twenty-two (22) different surveyors, and updated in 1825. It was the first official atlas of the state of South Carolina. Since Greenwood County was not established in 1825, there is no map of it in the Mills Atlas.

After the U.S. Civil War, many counties created their own maps showing railroads and key county roads. The first known "road map" for the entire state was created in the 1910s, and with the establishment of the State Highway Commission in 1917, their first "road map" was published by the State in 1919. By the 1930s, the State Highway commission was maintaining individual county road maps. This Author has only been able to locate a few digital maps online, so far. As more are found for Greenwood County, the Author will add them here.
