Notes

The directory says ‘map viewers + Beacon, not a centralized catalog’. True of the UI, but the county runs a public ArcGIS Enterprise with a queryable REST directory and 118 public feature services. Suggest API = Y.
The Tax Parcel Viewer linked from the county site (Experience 228579a2…) is owned by HOCCPP16, in the ‘HOCCPP - Regional Planning’ org (6x801hFkTeoDflcw, 48 public feature services), the Herkimer-Oneida joint planning program.
The PARCELS folder also holds Herkimer County parcels (HC_TAX_PARCELS).
Other HOCCPP hubs: hoctc-hoccpp.hub.arcgis.com (0 items), hoctc-safety-action-plan-hoccpp.hub.arcgis.com.
Likely name collision: ‘Oneida County COVID-19 Update’ Hub (owner OCHDWI) reads as Oneida County, WI from the owner name; not verified. Excluded either way (not a catalog).
