There are several locators that you can use in ArcGIS Pro. Some examples of why you might use a locator are if you will be geocoding a set of addresses once a month for a monthly report, if you need to convert a table of client locations that contains sensitive information into a collection of points behind your organization's firewall; or if you need to identify what is near the water pump stations throughout the county using your organization's authoritative reference data.
The locators described below can be used across the ArcGIS platform.
ArcGIS Online World Geocoding Service
The ArcGIS Online World Geocoding Service includes support for a wide variety of content, has the latest features, and is up to date and ready to use. You can use it in ArcGIS Pro when you're signed in to your organization's portal, and it has been enabled for use. When using the ArcGIS Online World Geocoding Service, your addresses are sent to Esri’s cloud hosted World Geocoding Service for geocoding. Considerations should be made for an on-premises product if there are privacy or security requirements that require an on-premises solution, or if a transaction-based business model won’t work for your organization.
World Geocoder for ArcGIS
Organizations that have a global geocoding requirement and have privacy or security requirements that require an on-premises solution or a need for high-volume geocoding globally can use the World Geocoder for ArcGIS. This is the on-premises version of the ArcGIS Online World Geocoding Service Service and can be licensed and hosted behind a firewall. See World Geocoder for ArcGIS overview for more information.
StreetMap Premium for ArcGIS
Organizations that have privacy or security requirements, such as HIPPA, that require an on-premises solution or a need for high-volume geocoding in specific regions or countries can use StreetMap Premium for ArcGIS. StreetMap Premium can be licensed for ArcGIS Enterprise or for ArcGIS Desktop single or concurrent use. See StreetMap Premium for ArcGIS overview for more information.
Build your own
Organizations that collect and manage their own asset and address data that they need to search can build their own locator. There is flexibility in this option to set up geocoding in a way that individuals in an organization can search their data and know they can rely on any of the locators mentioned above if necessary.
All locators stored locally on disk (including World Geocoder for ArcGIS, StreetMap Premium for ArcGIS, and locators your create) can be added to an ArcGIS Pro project in the same way. Right-click the Locators folder in the Catalog pane, and click Add Locator. A dialog appears, and you can browse to the location of your locator on disk to add it to the project. Once added, it functions in the same way as a service that has been added automatically.
