Our use of GIS in elections started with redistricting. GIS was used very effectively by our State Reapportionment Commission in 2001 and 2011. They used GIS to balance district populations and to create a series of paper maps showing the new district boundaries. In 2011 they also published online maps so the public could more easily see where the new boundaries were being drawn.

After redistricting, each of our counties needed to create new precincts and correctly assign voters to these new precincts. The voter management system in use at that time used street segments and address ranges to assign voters to precincts. Without GIS, this was an intensive manual process to examine the streets and determine the new address ranges for the new precincts.
