Parcels

The mission of the Statewide Parcel Map Program is to collect, assemble, maintain, and provide access to statewide tax parcel GIS data.

Publicly available GIS tax parcel data is available for Download or as Web Services. You can also use the NYS Assessment Look-Up Tool to put in an X, Y coordinate within New York State and get assessment data information for that location. These standardized parcel datasets are updated once a year. 

While we encourage counties to open their parcel data publicly, we respect each county’s right as the data owner to control the distribution their GIS data. Please contact the county (see resource links below) to obtain GIS parcel data that is not currently open and available to the general public.

Parcel centroid data for all 62 New York State counties. Parcel centroids were generated using the NYS Office of Information Technology Services Geospatial Services Statewide Parcel Map program data. Attribute values were populated using Assessment Roll tabular data Geospatial Services obtained from the NYS Department of Tax and Finance's Office of Real Property Tax Services (ORPTS).

Tax Parcel Centroid Data is available as a web service: https://gisservices.its.ny.gov/arcgis/rest/services/ or as a data download.

GIS tax parcels determined to be owned by the State of New York in all 62 counties. This designation was based on the tax assessment owner name, internet research, and work with individual State agencies. The State agency that owns and/or operates the tax parcel is also identified. Refinement of this dataset is on-going.

(Revised November 2024) 

The Statewide Parcel Map program is the formalization of work that has been going on in New York for more than a decade.

As far back as 2004, the NYS Geospatial Advisory Council identified tax parcel boundary and land ownership information as one of three framework data sets necessary for governments to effectively use and benefit from GIS technology.

During 2007-2008, the Office Cyber Security and Critical Infrastructure Coordination utilized a USGS CAP grant to develop the NYS GIS Strategic Plan. The Geospatial Advisory Council and the NYS GIS Association collaborated.  In addition to identifying very high demand for parcel data across the stakeholder community, the plan's recommendations included five prioritized initiatives that would advance the geospatial programs within the state. The highest priority recommendation was to "[f]ormally pursue a program to develop a statewide parcel data layer…" (p.38)

In 2011, the Office of Cyber Security utilized another CAP grant to develop the Business Plan for Centralized Access to Consistent Cadastral Data which identified that at least a dozen NYS agencies undertake independent efforts to gather, standardize and utilize tax parcel data. It also identified "enormous barriers" to gaining universal acceptance of sharing and standardization of the data.

In 2014, the NYS Information Technology Services (ITS) GIS Program Office (GPO) created the Statewide Parcel Map Program and began the work of collecting GIS tax parcel data from counties and incorporating it into a statewide dataset under a common data schema for release to the public. 

As of 2023, the GPO is now NYS Geospatial Services under the ITS Chief Data Office (CDO). The Statewide Parcel Map Program continues to create a yearly standardized parcel dataset and shares it as widely as each county, as the parcel data owners, allow it to be shared.
