Notes

Change from the directory (“No general catalog found”): there is a county-run ArcGIS Enterprise Site with Data, Documents and Apps & Maps tabs. Its Data collection is thin, though: 1 dataset, “Orange County Parcels” (146,065 features). The public ArcGIS Server also exposes folders for tax parcels (DTP2023–2025), planning, legislative and school contacts, and more.
A Requests/Downloads page is at https://gis.orangecountygov.com/mra. It was not opened.
Excluded: data-ocpw.opendata.arcgis.com is OC Public Works, Orange County, California. data-orangecountygis.hub.arcgis.com is Orange County, Virginia (Audit 2026-11-05). Other Hub sites named “Orange” are FL, CA and MA.
Topical NY hubs from org ocnygis: https://openspace-ocnygis.hub.arcgis.com/ (“Open Space Plan: Orange County, NY”, HTTP 200) and the Orange County Transportation Council site.
ocgis.orangecountygov.com (the old link on the county page) does not respond.
