The Office of GIS Interactive Mapping Viewer has been experiencing a few problems with the layer displays and printing functionality. As we work on correcting these issues, please feel free to try this alternative site. This site has the same data layers and print and search functionality as the original. It does not have the reporting functions.

To gain access to the main site please click HERE.

NOTE: The Division of GIS will be conducting system upgrades to our servers on March 13th, 2024. Unfortunately, this may result in the GIS Interactive Mapping Viewer being unavailable for a few hours. We thank you for your patience.

We hope that you find this new version of the OnMap application to be a valuble upgrade. We look forward to receiving your comments on this at Erie County GIS Office

NOTE: The Office of GIS announces that the direct link from the parcel attributes to the Erie County Tax Inquiry application is no longer available. We have been informed that the old application has been replaced by a newer, more secure, application which does not support 3rd party queries. We will replace the link that goes directly to the parcel information to the general site. From there you can query the application for the parcel in question. We apologize for this inconvenience.

Bookmarks should point to to eliminate broken links when project updates are completed.

Problem reports or general comments can be emailed to Erie County GIS Office
