The mission of Cobb County's Geographic Information System is to create, operate, and maintain an efficient, cost-effective geographic information system through the use of specialized computer, mapping and digital aerial photography technologies in support of the Board of Commissioners, elected officials, and county departments. Cobb's GIS will collaborate with other government and non-government entities to provide responsive and useful location-based services to customers.

In simple terms, the GIS staff is tasked to create a comprehensive and accurate digital computer map of the county. This digital computer map will contain technical and business information about locations and events within the county that will have value to many potential customers. The data contained in the GIS are to be accessed by the county user departments and eventually by other GIS partners and customers.
