A vector polygon GIS file of county boundaries in New York State up to, and using the shorelines of, major hydrographic features. The file was originally a compilation of U.S. Geological Survey 1:100,000-scale digital vector files and NYS Department of Transportation 1:24,000-scale and 1:75,000-scale digital vector files. Boundaries were revised to 1:24,000-scale positional accuracy and selectively updated based on court decisions. Currently, boundary changes are made as needed based on authoritative sources.

This file contains 2021 parcel data only for NY State Counties which gave the NYS GIS Program Office (GPO) permission to share this data with the public. To date, 30 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. Attribute values were populated using 2021 Assessment Roll tabular datathe GPO 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 parcel data comes from NYC MapPluto(https://www1.nyc.gov/site/planning/data-maps/open-data/dwn-pluto-mappluto.page)

A vector polygon GIS file of all city and town boundaries in New York State. The file was originally a compilation of U.S. Geological Survey 1:100,000-scale digital vector files and NYS Department of Transportation 1:24,000-scale and 1:75,000-scale digital vector files. Boundaries were revised to 1:24,000-scale positional accuracy and selectively updated based on municipal boundary reviews, court decisions and NYS Department of State Local Law filings for annexations, dissolutions, and incorporations. Currently, boundary changes are made based on NYS Department of State Local Law filings (http://locallaws.dos.ny.gov/). Additional updates and corrections are made as needed in partnership with municipalities.
