Geographic Information System

A geographic information system, or GIS, is a computer system for capturing, storing, checking, and displaying data related to positions on Earth’s surface. GIS can show many different kinds of data on one map, such as streets, buildings, and vegetation. This enables people to more easily see, analyze and understand patterns and relationships.

The GIS group develops, maintains and implements databases and web applications for the district and division offices. They also provide technical advice to fellow employees and customers for all matters relating to GIS.
