Rockingham County parcel REST endpoint not yet listed.
Rockingham County does not have a verified public ArcGIS REST parcel endpoint in our directory. Many counties run their parcel layers on the assessor's portal or behind a viewer-only interface. If you know the URL, send it in.
No token-free public REST endpoint exists for Rockingham County parcel data. The same authentication barrier that blocks Hillsborough County applies here: NH GRANIT's statewide NH Parcel Mosaic (nhgeodata.unh.edu/nhgeodata/rest/services/CAD/ParcelMosiac/MapServer) returns HTTP 499 without a valid GRANIT token. Rockingham is New Hampshire's most populous county (pop. 330,000), covering Portsmouth, Salem, Derry, Londonderry, and the southern tier of Manchester suburbs. Individual municipalities use fragmented vendor solutions -- Vision Government Solutions hosts assessor data for Salem, Derry, and several others; AxisGIS serves Rye, Deerfield, and others -- but none expose a standard queryable ArcGIS FeatureServer. For programmatic owner-level access, a GRANIT account (granit.unh.edu) is required. Regrid covers NH at commercial tier. The Rockingham County Registry of Deeds (ecourt.rockinghamregistry.com) is publicly searchable for recorded instruments but does not expose a REST parcel layer.

Rockingham County does not yet have a verified public REST endpoint in our atlas. The sections below cover patterns common to most county parcel APIs.
/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 Rockingham County actually publishes, not what you might expect from a national standard (there isn't one).

Not in our atlas yet. Rockingham County either runs a token-gated server or a viewer-only portal. If you know a public ArcGIS REST URL for it, send it our way and we'll add it.
