Making Available to your team

You will need to ensure that the content item is shared with all the users who need to access the Locator.

For example, you may need to click “Share” and select the whole “Organization“.

You will need to be an ArcGIS Administrator to add to your whole organization.

1. Go to the “Organization” tab;

2. Click the “Settings” tab;

3. Select “Utility Services” from the left-hand menu;

4. Under the “Geocoding” section, select “Add Locator”.

After clicking “Add Locator”, select “From Existing Locator”.

For “Locator Item” select the new Locator from the dropdown. You can change the Locator name and placeholder text if required.

Alternatively, select “From URL” and specify the URL of the Locator Content item added in the previous step (to get this URL click on the Locator in Content and on the Overview tab copy the URL in the bottom right).

The new Locator will now appear in the list of Locators.

To verify the Locator is now working, go to the ArcGIS Online Map Viewer Classic by selecting the “Map” tab and from the search dropdown what3words should appear in the list.

In case users open the “Map” in the new ArcGIS Online Map Viewer, to display the what3words locator, click on the search icon on the right-hand sidebar, the search bar will appear at the top and from the search dropdown what3words should appear in the list.

Troubleshooting

I get an error when adding the Locator as a Utility Service for my Organization

Make sure that the Locator is shared with your whole organization. See step 3 above – go to the Locator Content Item and click “Share”

I've added the Locator but I don't get any 3 word address results when searching

When you are searching for a 3 word address if no addresses are found then please ensure you are using your what3words API key
