The Geographic Services department in the Division of Property Assessments serves and assists all 95 Tennessee counties with delineating County Commissioner Districts - a process known as local Redistricting* - and with delineating Voter Precincts.** This department is also the Tennessee State liaison to the U. S. Census Bureau's Redistricting Data Program.
At the core of these services is the use of Geographic Information Systems (GIS) technology. GIS allows this department to house all Voter Precincts, Commission Districts, and Census data in a relational database. These data can then be used for a range of activities, from mapping to analysis, thus enabling this department to more efficiently and accurately assist the County Officials and Administrator of Elections.
