Notes
- Change from the directory (API N): the county page now links a public REST Services Directory. Its folders are Data, Hosted, Parcel_Fabric, Parcel_Viewer, REConnect and Utilities, and the
Parcel_Viewer/Tax_Parcel_DataMapServer answers queries. The page is still a static list, not a catalog. - Downloads include tax parcels (85 MB ZIP,
ucis-gis.s3.us-east-2.amazonaws.com/Parcel-Data/202607/), contours (shapefiles and a 7 GB GDB), surface water, election districts, legislative districts, zoning and habitat cores. The page also links third-party data: NYS Clearinghouse, CUGIR and others. - Custom data requests carry a minimum charge of $154.80, per the page.
- Topical Hub sites (“Ulster County Transportation Resiliency Project”, Route 9W plan) are not catalogs. “Mid Ulster” sites are Northern Ireland.
