Data Warehouse

Westchester County datasets are available for download.  Please browse the web pages below to view available datasets.


County Data Download

 

Countywide datasets are grouped by theme (district and boundaries, community facilities, environmental features, planning, transportation and census boundaries). Data can be downloaded in either a zipped ESRI shapefile or a Google Earth KMZ file. These datasets were developed by Westchester County GIS or are based on data obtained from other organizations. Users are encouraged to review coverage metadata.

Municipal Tax Parcel Data

 

In cooperation with local governments, Westchester County GIS is providing digital tax parcel data online for download. An interactive Municipal Tax Parcel Viewer is made available online that allows users to identify parcel data by address, print key or owner name (if available). Users can also print maps, export a query result, and generate mailing labels needed for an ‘abutters’ notice.
