We only call a field restricted when there is a stated reason we can cite. Everything else here is a fact about the services we index, not a claim about the law.

Westmoreland County, Pennsylvania (Greensburg; FIPS 42129). The county's own ArcGIS Enterprise 11.5 server (gis.westmorelandcountypa.gov), layer 2 'Parcels' of Upgrade/Parcels_AS400_VIEW_Upgrade MapServer: 191,739 parcels, county-only, so no scope clause is needed. The service is an export of the county's AS400 assessment system with 168 fields; the same service holds layer 0 'Lot Lines' (198,105) and layer 1 'Symbol Lines'. The parcel id is PARCELID (also UPI, MAP15 and PAR_ID); the owner is NAME (191,196 of 191,739 rows populated, 99.7%) with CO (care-of, 5,007 rows) and the grantors GNTR1 to GNTR3 on sale records; the situs is SITUS (191,196 populated; also FULL_ADDRESS, NUMBER, STR_NAME and TWNSHP_NAM); the owner mailing address is STREET1 (182,013 populated) with STREET2, CS (city), ST, ZIP (an integer column) and ZIPSFX. OWNER-NAME TRAP: NAME is a fixed-width 30-character string padded with trailing spaces, and the other text columns are padded the same way (STREET1 also starts with a space), so an exact NAME = 'X' never matches and every value comes back padded: search with UPPER(NAME) LIKE 'SMITH%' (a prefix, as the sample query does) or LIKE '%SMITH%', and trim the result. The server rejects TRIM() in a where clause (error -2147220985), so the padding cannot be stripped server-side. NAME is cut at 30 characters, so a long owner name or a joint owner can be truncated. The UrbanKit owner search wraps the term as UPPER(field) LIKE UPPER('%term%') and enrichment trims owner values, so neither is defeated by the padding; only a hand-written exact match is. ZIP is an integer, so ZIP <> '' errors: test it with IS NOT NULL. maxRecordCount is 2,000 with pagination. CORS: the server echoes the request Origin in Access-Control-Allow-Origin. CURRENCY: UPDATEDATE is stale (newest 2011-04-11) and the layer publishes no editing info, so neither is a currency signal; the sale fields are: SD1YR = 2026 on 7,011 parcels (read 2026-10-12), 775 of them with SD1MO of 9 or later and 81 of 10 or later, and SD1YR = 2025 on 9,610, so the assessment feed is live. DURABILITY: the service sits in a folder named 'Upgrade' and its name ends in _Upgrade, so the URL may move when the county finishes the upgrade; if the liveness probe flags this record, list the county server root for the Parcels_AS400_VIEW service. A sibling folder (GIT_Testing) requires a token. The statewide PASDA parcel layer does not include Westmoreland (39 sources, none of them Westmoreland) and carries no owner column, so this server is the only REST source. Unofficial ArcGIS Online copies exist (197,404 rows, edited 2026-10-01) and are not used. The county GIS page (westmorelandcountypa.gov/141/GIS) returned HTTP 403 to a scripted fetch, so the license terms were not read.

Westmoreland County's Parcels layer exposes parcel identifiers (Parcel ID, Uniform Parcel Identifier), owner names (Owner Name (30-character padded)), and address fields (Situs Address). Use it for owner-name lookups and address-based parcel searches. 4 of 10 listed fields accept queries; the rest are returned on read but not indexed for search. Served as an ArcGIS MapServer layer, which supports query operations but not write operations; last verified 2026-10-12.
/query?where=…&outFields=*&f=jsonto the URL. The sample query above is a working example you can paste into a browser tab to see the raw JSON response.Counties publish parcel data through their own ArcGIS Server installations, each with its own schema. One county uses APN, another uses PIN, a third uses PARCEL_ID. Some expose owner names; others keep them on a separate assessor's portal. The searchable fields list above reflects what Westmoreland County actually publishes, not what you might expect from a national standard (there isn't one).

gis.westmorelandcountypa.gov serves Westmoreland County, Pennsylvania parcels over public ArcGIS REST, but, like most county servers, it may not send the CORS headers a browser needs for a cross-origin fetch. If a direct browser call fails, the layer still works from curl, Postman, or a server-side script; the UrbanKit parcel lookup tool proxies the request, so a search that succeeds there confirms the layer is genuinely public.
We last verified Westmoreland County's MapServer layer on 2026-10-12. County GIS teams move services without notice, so if you hit a fresh 404, tell us and we'll re-check. Atlas entries are re-verified on a rolling basis.
Westmoreland County's layer is hosted by the county on gis.westmorelandcountypa.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but gis.westmorelandcountypa.gov can throttle heavy automated traffic at the host level. Page through results with resultOffset / resultRecordCount and request only the fields you need. There's no API key and no charge from the county.
