Publication Date: APR 2018. A vector polygon GIS file of all county 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 court decisions. Currently, boundary changes are made as needed based on authoritative sources. Additional metadata, including field descriptions, can be found at the NYS GIS Clearinghouse: http://gis.ny.gov/gisdata/inventories/details.cfm?DSID=927.

A listing of NYS counties with accompanying Federal Information Processing System (FIPS) and US Postal Service ZIP codes sourced from the NYS GIS Clearinghouse.

Publication Date: November 2017. This file only contains parcel data for NYS State-owned tax parcels. 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 2016 Assessment Roll tabular data the NYS GIS Program Office (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. New York City attribute data comes from NYC MapPluto (https://www1.nyc.gov/site/planning/data-maps/open-data/dwn-pluto-mappluto.page). Parcel polygons range from 2014 to 2017.

The State-owned tax parcel polygons in this file are the result of a best effort selection based on the Primary Owner and Additional Owner fields in the NYS Statewide Tax Parcels file, GPO data, State agency data, and online research. These same data and information are also the basis for a best effort assignment of a NYS agency name (listed in the NYS Name field) to most tax parcel polygons where the Owner Type field value is State. The NYS Name Source field consists of a code that describes how the State-owned designation and agency name were determined, if this was verified, and the means of verification, if applicable. Additional metadata, including field descriptions, can be found at the NYS GIS Clearinghouse: http://gis.ny.gov/gisdata/inventories/details.cfm?DSID=1300.

Dataset consist of statutory boundaries of Significant Coastal Fish and Wildlife Habitats (SCFWH) as identified and recommended by Environmental Conservation and designated by Department of State. All SCFWH areas are found within the federally approved Coastal Area Boundary (CAB) of New York State. Original data was hand-drawn over DOT topographic quadrangle sections and filed with local governments. Digital data set (version 1.1) was previewed by NYS DEC Habitat Inventory Unit and subsequently corrected as per their recommendations. The original digital version of the SCFWHs, Version 1.2, has been replaced with this current version 2.0. Version 2.0 includes changes/updates to the Peconic estuary (2002), north shore of Long Island (2005), the south shore of Long Island (2008), and the Hudson River (2012). Scale: 1:24000. Data was last revised by the NYS Clearinghouse Office of Planning and Development August, 2013. The data was downloaded from the New York State GIS Clearinghouse September 2015.

This Basic Viewer is intended to allow users to view datasets maintained by NYS Geospatial Services. These layers are pre-loaded -- to explore our datasets, select the “Layers” button. Visitors can also add data from the GIS Clearinghouse, URL data layers, or their own local GIS data by selecting the “Add Data” button. Where counties share their parcel data, parcels may be viewed as well.The Basic Viewer App now includes a Surveyor Bookmark with reference data and survey information. This bookmark allows for a quick way to display data and layers that Surveyors may find useful - NOAA CORS, NGS Sheets, Hillshade, and more.
