This file contains 2020 county parcel data. The county has given the NYS GIS Program Office (GPO) permission to share with the public.
Parcel geometry was incorporated as received from County Real Property Departments. No attempt was made to edge-match parcels along adjacent counties. County attribute values were populated using 2020 Assessment Roll tabular data the GPO obtained from the NYS Department of Tax and Finance’s Office of Real Property Tax Services (ORPTS). This tabular data was joined to the county provided parcel geometry using the SWIS & SBL or SWIS & PRINT KEY unique identifier for each parcel. Detailed information about assessment attributes can be found in the ORPTS Assessor’s Manuals available here: https://www.tax.ny.gov/research/property/assess/manuals/assersmanual.htm. New York City parcel data comes from NYC MapPluto: https://www1.nyc.gov/site/planning/data-maps/open-data/dwn-pluto-mappluto.page
