How to Request GIS Data from Ontario County
The GIS Program produces a wide range of data, some specific to projects in particular departments, while other larger layers such as parcels and street centerlines are maintained regularly for countywide application. If you are interested in obtaining digital GIS data, please complete the Data Sharing Agreement and return this by email to the GIS Coordinator, Sheri Norton. The County's adopted Data Sharing Process and Fee Schedule can be found here.

Please note that many of the data sets used were obtained from other organizations (e.g., wetlands, geology, etc.). If you are interested in these layers and the County is not the formal owner, a referral will be provided.
