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.
We provide Geographic Information support to all government agencies, citizens, community organizations, and many others.
Information and geographic support include, but is not limited to:
Why GIS?
Nearly 80% of information housed in government is geographic in some way. In order to make informed and accurate decisions, all geographic information involved with a certain area must be known and understood. Efficient delivery and presentation of this geographic data is what we are all about.
Our ultimate goal is to make County GIS information accessible from anywhere, by whoever needs it.
