Developing Infrastructure for a State-wide Mapping Program in the State of Georgia
Defining Issue: Develop a multiagency federal and State Joint Funding Agreement (JFA) to support a coordinated State-wide mapping program. GIS Solution: The Georgia Department of Community Affairs (DCA) organized and negotiated a consortium of thirteen federal and State agencies to jointly fund the development of State-wide coverage of digital othrophoto quarter quadrangle (DOQQ) images and digital elevation models (DEMs). Methodology: The Georgia DCA organized and negotiated a Joint Funding Agreement between the USGS and twelve other federal and state agencies in Georgia for the development of a State-wide coverage of over 4,000 digital othrophoto quarter quadrangle (DOQQ) images at a nominal scale of 1:12,000 and over 1,000 digital elevation models (DEMs) at a nominal scale of 1:24,000. Achieving the JFA was a complex process requiring over a year of negotiating eighteen separate contracts. The preceding education and marketing effort extended the planning and contract negotiation period to fully two
years. Delivered components of this massive, large-scale digital database have already revolutionized related GIS activities in the State. The DOQQs and DEMs have become the first two of a set of core GIS basemap layers for transportation, hydrography, and boundaries that have been proposed for State-wide development by the State's GIS Advisory Committee (GISAC), an executive-level planning council of State agencies. These JFA funded data are already being used for such far-ranging applications as transportation, planning, public health, environmental monitoring, forestry, land use and cover mapping, and natural and cultural resource management. DCA in conjunction with GISAC and its Georgia GIS Data Clearinghouse are presently developing policies and strategies to distribute these data to other government agencies, industry, and the general public. Software: The software systems include Esri's ArcInfo, ArcView, and ERDAS Imagine.
