The primary responsibility of the Digital Cartography and Precinct Demographics Section is to provide technical assistance for digital mapping and the development and modification of legislative plans for various political districts. South Carolina Election Districts include voting precincts, county councils, municipal councils, school districts, state house, state senate, and US congress.

In preparation of the redistricting process for S.C., the Digital Cartography section has partnered with the S.C. General Assembly to establish basic criteria for redistricting. These criteria are based upon constitutional requirements, voting rights regulations, and principles defined through subsequent judicial court rulings.
