Querying Parcel Shapes & Zoning Data via ArcGIS REST APIs

jaminhardik

Hi All,

I am new to the ArcGIS Location platform and wanted some guidance on API(s) for a project.

Is the following workflow possible through the ArcGIC Location Platform REST APIs in a single sequence:

1. Geocode a street address to get Lat / Long coordinates

2. Retrieve the Parcel Boundary Polygon & APN / AIN by querying a feature layer (e.g. from Living Atlas) using those coordinates

3. Intersect with Zoning data to pull localized features like Zone Code, Setbacks, FAR etc. (can be specific to a state / county area)

4. Have the polygon overlay on a satellite image basemap for that parcel

Are there specific reliable REST endpoints recommended for this? Also, is a direct Feature layer query sufficient for the zoning intersection, or is the Spatial Analysis service required?

Thanks!

Hi @jaminhardik,

Yes. It is possible to achieve this workflow using ArcGIS REST APIs. 

You need to use the Geocoding service to get coordinates from the given address. You can refer to the link for more info.
https://developers.arcgis.com/rest/geocode/find-address-candidates/

Use a Feature Layer query with the returned point geometry to retrieve the parcel polygon and attributes such as APN/AIN:
https://developers.arcgis.com/rest/services-reference/enterprise/query-feature-service-layer/

For zoning, another Feature Layer query is usually sufficient if you only need the zoning polygon that intersects the parcel. Spatial Analysis is not required unless you are doing larger overlay workflows or generating derived outputs:
https://developers.arcgis.com/rest/services-reference/enterprise/query-feature-service-layer/

Display the parcel polygon over the imagery basemap using the Basemap Styles service:
https://developers.arcgis.com/rest/basemap-styles/

Example workflow:
Geocode address -> Query parcel layer -> Query zoning layer -> Display parcel polygon on imagery basemap

One thing to verify is the availability of parcel/zoning data. In many cases, authoritative parcel and zoning layers come from county/city services rather than Living Atlas.
