Using the what3words ArcGIS Locator across the ArcGIS platform

easy

The what3words ArcGIS Locator brings the functionality of the what3words API to the ArcGIS platform. You can use the Locator throughout the ArcGIS product suite wherever a custom locator can be added. This includes ArcGIS Desktop – ArcCatalog and ArcMap as well as ArcGIS Pro.

On web, you can use the Locator within ArcGIS Online and any products able to connect to Online such as in app using Survey123. Or for GIS developers the ArcGIS APIs and SDKs in the Developer suite can harness the ArcGIS Locator as a REST API.

The Locator gives you the ability to convert to and from coordinates, or more commonly known within ArcGIS as forward/reverse address geocoding. Functionality varies by ArcGIS product so take a look at our tutorials to see how the locator works within ArcGIS.

You will need a what3words API key to complete this tutorial.

Yes. Our ArcGIS locator provides the same response as our API does for a record in China. You will need to make sure you display the 3 word address in the correct coordinate system that matches your other datasets. If you display the 3 word address on a map, make sure the map is a licensed Chinese map using the correct coordinate system. The standard ArcGIS Online map will work for this purpose.
