Service Description: Publication Date: June 2021. Updated annually. This map service has two layers: 1) NYS_Tax_Parcels_Public, and 2) NYS_Tax_Parcels_Public_Footprint which contains polygons representing counties for which tax parcel polygons are available in the NYS_Tax_Parcels_Public layer. County footprint polygons display when zoomed out beyond 1:37,050-scale. Tax parcel polygons display when zoomed in below 1:37,051-scale. The NYS_Tax_Parcels_Public layer contains primarily 2020 parcel data only for NY State counties which gave the NYS GIS Program Office (GPO) permission to share this data with the public. Work to obtain parcel data from additional counties, as well as permission to share the data, is ongoing. To date, 26 counties have provided the GPO permission to share their parcel data with the public. Parcel data for counties which do not allow the GPO to redistribute their data must be obtained directly from those counties. The GPO’s goal is to eventually include parcel data for all counties in New York State. 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: New York City data comes from NYC MapPluto which can be found here: For field descriptions, see NYS-Tax-Parcels-Data-Dictionary.pdf available for download in the Supporting Documentation section on this page: Attributes are the same for all GPO NYS Tax Parcel datasets. Thanks to the following counties that specifically authorized the GPO to share their GIS tax parcel data with the public: Cayuga, Chautauqua, Cortland, Erie, Genesee, Greene, Hamilton, Lewis, NYC- Bronx, NYC- Kings (Brooklyn), NYC- New York (Manhattan), NYC- Queens, NYC- Richmond (Staten Island), Ontario, Orange, Oswego, Putnam, Rensselaer, Rockland, Steuben, Sullivan, Tioga, Tompkins, Ulster, Warren, and Westchester. Geometry accuracy varies by contributing county. This map service is available to the public.
