Data Updates!
NYS Assembly, NYS Senate, and NYS Congressional (US House of Representatives) web services have been updated
NYS Assembly and NYS Congressional (US House of Representatives) now include the formerly “Planned” boundaries of 2024. All 3 have been updated in their attributes, with the winners of November elections being sworn in January 2025. The former services “NYS Assembly Planned 2024” and “NYS Congressional Planned 2024” have been taken down, as those boundaries are now reflected in the above.

What is GIS?
A Geographic Information System (GIS) is essentially a combination of maps and databases. GIS is a computer-based tool that can be used to capture, create, store, interpret, analyze, and visualize spatial data. Uses range from simple (viewing parcel data) to complex (criteria-based site selection for a proposed development). GIS is widely used and relies on data and information from many sources. The NYS GIS Clearinghouse helps connect users with GIS data, information, and fellow GIS users. To learn more, see our frequently asked questions (FAQs) or contact us.
