SAGIS is focused on providing access to geospatial data in a standardized format to all interested parties. SAGIS works with the City of Savannah, Chatham County, the Metropolitan Planning Commission and a variety of other government, non-profit, and private organizations to maintain standards, manage data, educate, and coordinate projects that affect the greater Savannah - Chatham County area. SAGIS shares this geographic data with the public through the SAGIS Map Viewer and Open Data. We also support geospatial education in our community through the organization of GIS Day Savannah every year.

SAGIS is governed by the SAGIS Board, which consists of the City Manager of the City of Savannah, the County Manager of Chatham County, a representative from Georgia Tech - Savannah, and a number of rotating seats that are appointed by the permanent members of the board.
