The South Carolina Geodetic Survey ensures the integrity of geodetic control throughout South Carolina so that land and land-related items can be accurately referenced to the national horizontal and vertical coordinate system. The SCGS accomplishes this by operating a statewide Real-Time GPS Network and upgrading county geodetic networks.
The SCGS's county aerial orthophotography program begun in 1986 was the catalyst for creating and maintaining an accurate, up-to-date, uniform statewide mapping system on a county-by-county basis. This digitized map base is the foundation for county and state computerized land information systems that facilitate manipulating and storing land records for a multitude of purposes.
The SCGS also re-establishes indeterminate political boundaries to ensure jurisdictional integrity which avoids costly litigation.
