This study examines the use of online geographic information systems (GIS) by North Carolina county governments. The study was conducted to investigate what web GIS services North Carolina counties offer, to determine how much these services are used and by whom, and to uncover how offering these services has impacted agency functioning. The counties examined were Wake County, Lee County, Guilford County and Robeson County. Methods employed over the course of the study included analyzing trends in web traffic statistics and interviewing staff members of participating agencies to uncover organizational changes occurring post-deployment of a web GIS. Trends in web GIS use were not consistent across counties. The chief impact of offering a web service was a decrease in walk-in traffic to agencies. This has freed up staff members to work on other projects. Employees also have taken on new roles as technology educators for web GIS users.
