Publication Date: April 2025. This polygon layer is updated annually.

This layer contains 2024 parcel data only for NY State counties which gave NYS ITs Geospatatial Services 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, 36 counties have provided the Geospatial Services permission to share their parcel data with the public. Parcel data for counties which do not allow the Geospatial Services to redistribute their data must be obtained directly from those counties. Geospatial Services' 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 2024 Assessment Roll tabular data Geospatial Services obtained from the NYS Department of Tax and Finance’s Office of Real Property Tax Services (ORPTS). Tabular assessment 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 data comes from NYC MapPluto which can be found here: https://www1.nyc.gov/site/planning/data-maps/open-data/dwn-pluto-mappluto.page.

These include:Living in areas particularly vulnerable to climate change (like communities along the coast or extreme weather)Coping with higher levels of existing health risks when compared to other groupsLiving in low-income communities with limited access to healthcare servicesLimited access to quality healthcareLimited availability of information and resources in a person's native languageLimited ability to relocate or rebuild after a disasterSource: https://storymd.com/journal/5mryx8nszj-health-disparities/page/93ld8c38vr-climate-change-and-health-equity

Polling locations in Ontario County, New York.

The New York State shoreline of Lake Ontario was classified in 2002 during the International Joint Commission's Lake Ontario - St. Lawrence River (LOSLR) water level regulation study based on 1 km reaches. The New York State Department of Conservation (NYSDEC) desired a more precise classification of the shoreline, and as a result AECOM reviewed 2012 oblique imagery provided by the US Army Corps of Engineers (USACE) to define detailed shoreline reaches. AECOM generated a spatially referenced feature class for shoreline classifications which represents a more precise version of the shoreline classification feature class generated during the 2002 LOSLR study. The 2002 LOSLR study was used as a baseline to generate classifications. For consistency, geomorphic classification and structural classification types from the LOSLR study were used. Creation Date: 06/13/12. Latest Modification Date: 08/15/12. This datalayer provides information obtained as a result of oblique imagery review for the entire coastline (excluding embayments) of the New York State portion of Lake Ontario.The shoreline was divided into reaches and this dataset represents the line features for those reaches for the U.S. shoreline of Lake Ontario, not including islands and embayments as coded by the LOSLR study in 2002. Each feature within the data layer produced by AECOM represents a reach of shoreline of differing classification. Classification reaches were not defined according to a set unit of measure. In some instances a shoreline classification may span a couple thousand feet, spanning multiple tax parcels. In other instances, multiple classifications may exist for a single tax parcel. Original shoreline boundary was taken from the CityTown.shp datafile from the NYS Civil Boundaries (database) provided by NYS Office of Cyber Security (NYSOGS) via the NYS GIS Clearinghouse website for the following counties: (Niagara, Orleans, Monroe, Wayne, Cayuga, Oswego). Original shoreline boundary was taken from the NHDFlowline.shp datafile from the National Hydrography Dataset (NHD) (database) provided by NYSDEC via the NYS GIS Clearinghouse website for the following counties: (Jefferson). The shoreline polyline was modified to most accurately represent the actual shoreline based on 2010-2012 Bing Maps aerial imagery.
