–2010 Indiana GIS Conference HISTORY

–2010 Indiana GIS Conference History First Polling Place Locator in late 1990’s. Original vision To locate a voter’s polling location based on their address. Used ArcIMS-based technology to display polling location information in a web application. Voter Information Portal (VIP) is the 4 th generation of the Polling Place Locator.

–2010 Indiana GIS Conference Challenges Geocoding Used fallback (composite) geocoding from parcels to streets. Unable to locate 100% of addresses in Marion County Missing information Match scores not meeting threshold set in locator In a few cases street range interpolation put the address coordinate in the wrong precinct.
