Data Resources
The GIS Program produces a wide range of data, some specific to projects in particular departments, while other layers such as streets and address points are maintained regularly for countywide applications. Many of these data, including parcels and LiDAR, are now available for web "mashup" and/or download via the Data Center.
If you need special layers and processing (e.g., conversion, custom area extractions), please download and complete the County's Data Sharing Agreement. If you have any questions you may call (585-396-4482) or email the GIS Coordinator, Sheri Norton.
