Geographic Information Systems (G.I.S.)
For over 20 years, the G.I.S. Division has been responsible for the annual production and maintenance of over 30,000 maps. This includes tax parcel maps in the County's plat books and election maps supporting elections held within the County. In addition, they provide numerous specialized maps to support many of the County's other agencies; including Stormwater, Transportation, Planning and Zoning, and Community Development.
But G.I.S. is much more than paper maps. At its core it provides the tools necessary to analyze the County's geographic-based databases to meet decision-makers' needs. For example, G.I.S. is being used by County stormwater engineers to determine flood risk for County properties. G.I.S. is also an integral part of the County's Office of Emergency Management's efforts to plan for and respond to emergency situations.
