The Delaware County Office of Geographic Information manages the County's Geographic Information System (GIS). A GIS is a computer-based mapping system which relates various types of data and information with real-world locations.

The Delaware County GIS Department has three primary goals:

• To efficiently create and maintain a state-of-the-art GIS which accurately and comprehensively represents all relevant and useful geographic data and information about the County
• To deliver this data to the general public, private sector clients, and associated governmental agencies
• To provide expert GIS consulting and application development

As an enterprise GIS, one key objective of the GIS Department is to seamlessly integrate GIS into the daily workflows of County and City Departments and partner organizations. In other counties and organizations, GIS integration has provided time and cost-savings, improved analysis capabilities, and enhanced decision-making capabilities. Therefore, in order to facilitate GIS integration, the GIS Department provides consulting services to its internal County agencies as well as its partner organizations. The GIS Department examines business practices for departments and develops recommended areas for applying GIS to daily tasks. Under certain circumstances, the GIS Department also will develop custom applications to meet the needs of County departments and partner organizations.
