A GIS is a computer system for management, analysis, and display of geographic knowledge. It can produce information that answers specific questions and allows you to share that information with others. By visualizing relationships, connections, and patterns in data, you can make informed decisions and increase efficiency throughout an organization.
Loudoun County was an early adopter of GIS, purchasing software from Esri, the GIS software company, in 1986. Today the county operates a distributed GIS that is integrated with the county's other information systems. A distributed system is one for which responsibility for data maintenance and analysis is shared among several departments.
The county's GIS has received numerous awards over the years. View the list (PDF).
