Geographic Information System (GIS) Division

A Geographic Information System (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. A GIS is often thought of simply as a mapping tool, however, a GIS also provides very powerful data analysis tools that support and improve decision-making and problem solving.

The Onondaga County Department of Planning's GIS division is responsible for building and maintaining the County's GIS. We create, acquire, and maintain a wide array of spatial data sets, maps, and applications that support government functions. The GIS has become an essential tool that is used by most County departments to maximize effectiveness and efficiency and improve decision-making.

The GIS Division provides extensive spatial data support to the City of Syracuse and towns and villages in the County. GIS staff also manage, distribute, and support the County's digital aerial photography program (Pictometry)
