OnCor is a cooperative project between the Ontario County Planning Department, Real Property Tax, Information Services/GIS Program, and the County Clerks Office. The program leverages the resources of these individual departments and delivers them through one common web enabled interface.

This project currently provides integration of County’s Land Record information (assessment data, deeds, surveys, aerial photography), and will evolve to address the needs of the Ontario County residents and visitors. You will find many tools for finding information, including dynamic access to other data such as Pictometry, Bing and Google Maps. Look for specialized sites in the near future such as recreation and community-focused applications. The Silverlight Viewer user guide can be found here, and the Mobile Viewer user guide can be found here.
