Questions, with answers

Hawaii parcel REST API, common questions

Which Hawaii counties publish a public parcel ArcGIS REST API?

2 Hawaii counties are indexed in the UrbanKit atlas with verified public REST endpoints: Kauai and Maui. Each exposes an owner-name field you can search directly on the public layer.

How do I search Hawaii parcels by owner name?

Kauai and Maui expose an owner-name field on the public REST layer. Kauai, for example, uses the owner field. A case-insensitive search is ?where=UPPER(owner)%20LIKE%20UPPER('%25SMITH%25')&outFields=*&f=json. Open a county's page here for its full field list and a ready-to-run sample query.

What is the ArcGIS REST URL for parcels in Kauai, Hawaii?

Kauai publishes parcels at https://geodata.hawaii.gov/arcgis/rest/services/ParcelsZoning/MapServer/9, a MapServer (layer 9). It indexes by Owner Name, Tax Map Key (9-digit TMK / APN), and County TMK (8-digit). Owner-name search: UPPER(owner) LIKE UPPER('%25SMITH%25').

Do Hawaii parcel layers use ArcGIS FeatureServer or MapServer?

Both. Hawaii uses a mix: Maui publish ArcGIS FeatureServer layers, while Kauai use MapServer. Both support /query, so the same owner, parcel-ID, and address lookups work against either.
