About Cobb GIS
Cobb County departments rely on information to carry out their various missions for public safety, community development, taxation, infrastructure management (e.g., buildings, roads, and water systems), parks and cultural affairs, and other government services. It is estimated that more than 80% of all government data contains a geographic component that can be referenced to a location on the earth’s surface. To manage this strategic asset, Cobb County employs technologies that include Geographic Information Systems (GIS) and Global Positioning Systems (GPS).

Cobb GIS 5-Year Plan:
The Enterprise GIS 5-Year Plan, which is refined on a yearly basis to accommodate changing county needs and new GIS technology, serves as the guiding document for the development, implementation and maintenance of the countywide, enterprise GIS.  It provides the mechanism to build a spatial information system that will hold and continue to supply information that is complete, accurate, and current.  The plan assists the citizens of Cobb County, Board of Commissioners, county staff, and the county’s governmental agencies develop an understanding of the key elements of the county’s Enterprise GIS, and it also serves as a template for other agencies seeking to implement or advance their GIS program.

Cobb GIS Highlights:
Continued annual update of the county’s highly accurate base map, consisting of color digital orthophotos, limited planimetrics, 2-foot contours, and a Digital Terrain Model

The creation of a multi-departmental workflow which facilitates the annual update of the Tax Assessor’s parcel maps (over 240,000 parcels) in a digital GIS format

CobbETRANS, the county’s intelligent GIS transportation network, has been updated with new roads in 2004 and 2005

Installation of a network of three Global Positioning System Continuously Operating Reference Stations (GPS CORS) in 2004 to improve the level of service and lower costs typically associated with survey work

Implementation of a Web-based mapping application, CobbWebMap, for the internet and intranet

Development of desktop and Web-based GIS applications to facilitate access to geospatial data

Construction of 3D models for selected facilities to enhance visualization of key areas

Development and update of departmental databases using the digital orthophoto base map

Future Goals:
Expand access to the information in the Enterprise GIS through the county's Intranet and the World Wide Web

Continue update of four cornerstone layers (digital orthophoto base map, 2-foot contours, parcels, and transportation network) and other enterprise GIS databases

Develop digital GIS zoning layer

Integrate GIS/GPS technologies with business applications, including mobile/wireless solutions
