GIS for Voter Registration Files

Geocoding voters' addresses is the best way to maintain an accurate and up-to-date statewide voter registration system, as required by the Help America Vote Act of 2002 (HAVA). With the help of GIS, the geocoding process assigns latitude and longitude coordinates to each address, thereby standardizing how voters' addresses are represented in a registered voter file.

Addresses can then be matched against streets on a digital map. After mapping voters' locations, precinct and district boundaries can be overlaid or redrawn while keeping an accurate account of voter assignments. Voter points or addresses can be color coded so that invalid precinct assignments can be easily identified.

"Identifying and correcting 'invalid precinct assignments' before county Registered Voter Files are converted or merged into a statewide database will improve the integrity of the statewide voter file as well as the street index files to be generated from the voter registration system."
