The Office of Information and GIS Services Department is the single point of contact for Delaware County's web-based applications and creates, maintains, and provides access to county GIS databases. In addition, the OOI-GIS Dept is integrated into the Delaware County Homeland Security and Emergency Management Agency, providing technical support, logistics and planning services, and incident response along with HSEMA staff to the public safety agencies in Delaware County.

Open Data

We have been working to make as much of the data we maintain available through web-based applications for ease of access and use. In addition, much of our data is available for download as well through our Open Data site located at: maps-delcogis.opendata.arcgis.com

What is GIS?

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

The Delaware County OOI has three primary goals:

• To efficiently create and maintain a state-of-the-art GIS that 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

The basis of Delaware County's GIS is its library of GIS data layers. These layers provide a comprehensive representation of the County's property fabric; basic infrastructure; environment; recreational facilities; governmental structure and facilities; emergency services infrastructure and facilities; and transportation network. 

These GIS data layers are developed and maintained by the OOI and other County Departments utilizing ESRI's suite of ArcGIS software. 

What do we do?

As an enterprise GIS, one key objective of the OOI 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 OOI provides consulting services to its internal County agencies as well as its partner organizations. The OOI examines business practices for departments and develops recommended areas for applying GIS to daily tasks. Under certain circumstances, the OOI also will develop custom applications to meet the needs of County departments and partner organizations.
