Create a locator

If you need to create your own locator to geocode against your own data, you can do so in ArcGIS Pro. Creating your own locator allows you to find places and addresses on the map using your own data just as you do using the ArcGIS World Geocoding Service.

The following steps describe how to create a locator using the Create Locator geoprocessing tool:

1. On the Analysis tab, click the Tools button .

   The Geoprocessing pane appears.

2. Select the Create Locator tool.
   1. In the Geoprocessing pane, click the Toolboxes tab.
   2. Click Geocoding Tools in the list of geoprocessing toolboxes.
   3. Click the Create Locator tool in the list of geocoding tools.

      

3. In the Create Locator tool pane, click the Role drop-down list and choose the role on which you want to base your locator.
For more information on choosing the right role for your data, see Primary locator roles.
4. Click the Browse button next to the Primary Table(s) text box.

   The Primary Table(s) dialog box appears.

5. Browse to the primary reference data you want to use in the locator and click Ok.
If you have more than one dataset that you want to use in your locator, you can repeat the process of adding data to the Primary Table(s) text boxes (more appear as needed) until all of the primary reference data you want to include in the locator shows in the tool.

Note:

In addition to your primary reference data tables, you may have tables containing information for alternate names of streets or cities. For more information about using alternate name tables to create your locator, see Fundamentals of alternate name tables.

Note:

When creating an address locator with reference data that contains millions of features, it is necessary to have at least 3 to 4 times the size of the data in free disk space on the drive containing your temp directory because files used to build the locator are written to this location before the locator is copied to the output location. If you do not have enough disk space, the tool will fail at some point during execution when it runs out of space. Also, keep in mind that when creating very large locators, you should have a machine with enough RAM to handle large memory-intensive processes.

6. Click the drop-down arrow in the Alias Name column and choose the proper field name to map fields in your data to fields expected by the locator role you have chosen.
7. An output file name and destination are automatically selected. To change these values, click the Browse button next to the Output Locator text box.

   The Output Locator dialog box appears.

8. Specify where to store the locator (the save location must be in a file folder), name it, and click Save.

   Tip:

   If you need additional information and reminders about any of the input categories on this tool, click any of the Information buttons next to the input categories.

9. You can set Optional parameters before you run to further customize your locator.

   Note:

   If you have Alternate Name Tables for any fields in your data, you can add them now and map the alternate name to the appropriate Role in your data.

   Note:

   If you have any fields in your data that you want to see returned with results that aren't mapped to locator fields for the role that you chose above, you can add those fields as Custom Output Fields. Any field that you add here will be included in your geocoding results.

   Note:

   You can also modify the Precision Type of your locator by selecting Global High, Global Extra High, or Local Extra High. For more information on this parameter, see the geoprocessing documentation for the Create Locator tool.

10. Click Run .

    

When the process finishes, the locator is added to the Locators folder in the Catalog pane. You can also find your locator in the save location you previously specified. You can add your newly created locator to a new or existing project.
