After a table of addresses is geocoded, you can review the results. If you are not satisfied with the results, you can use the interactive rematch tool in ArcGIS Pro to manually review addresses and select a new candidate. This process is called rematching.
An ArcGIS Online subscription is required to rematch unmatched addresses or automatically rematch all addresses in the geocoded feature class using ArcGIS Online World Geocoding Service. If you haven't signed in already, you'll be prompted to log in to your ArcGIS Online for organizations account. See how to connect to the ArcGIS Online World Geocoding Service for more information.
This topic covers how to interactively rematch addresses using the Rematch pane, but you can also rematch specific addresses or groups of addresses with SQL queries using the Rematch geoprocessing tool.
The following procedure shows you how to effectively rematch addresses in a geocoded feature class in ArcGIS Pro using the interactive Rematch pane:
- Right-click a geocoded feature class that you want to rematch, click Data, click Rematch Addresses , and open the Rematch pane. This allows you to view and examine addresses that failed to match as well as addresses that failed to match at or above a specified match level.
- Use the Rematch pane to review the unmatched or insufficiently matched addresses individually. The tool allows you to go through the addresses one by one, dealing only with the current problematic address.
- Inspect the input address, and correct it if there are errors. Sometimes certain addresses fail to match because of incomplete reference data. If necessary, you can inspect the input address fields for errors, update the fields with errors, and try geocoding the address again to get an updated list of candidates.
- Review the candidate list to see if you can find a possible match. Matching the address to a candidate in a reasonable proximity can be an option.
- You can also review and rematch addresses that tied or even addresses that matched if you're not satisfied with the match that your locator found automatically.
- For some addresses that could not find any candidates, but for which you know their location on the map, you can use the Pick from Map tool to match the address by clicking a location on the map.
The next section describes the Rematch pane. See the Rematch tutorial to learn more about a typical workflow for rematching a geocoded feature class and how to do it in ArcGIS Pro.
The Rematch pane is divided into several parts, which are explained in detail below. The parts group relevant data and tools together.
The top and bottom portions of the pane can be resized by resting the pointer on the line between the two parts of the pane. When the pointer changes to a resize cursor, you can click and drag to increase or decrease the size of the two parts proportionately. You can also click the arrow buttons on the right side of the line in the center of the pane to collapse the top or bottom portions of the pane. Once collapsed, you can click the arrow pointing in the opposite direction to expand that portion of the pane.
It is recommended that you generally keep both portions of the pane open simultaneously, since you need information in both portions of the pane to know which address you are rematching and the candidate to which you are geocoding the address.
Assess match success
You can view the total number of matched, unmatched, and tied addresses in the geocoded feature class to assess how complete your geocoding project is.
Your geocoded feature class is divided into three categories in the Rematch pane: Unmatched, Matched, and Tied. You can click any of the three tabs to see the total number of results in each category. In the example above, 46 addresses are in the Matched category. Although not pictured, the same example has 3 results in the Unmatched category and 1 result in the Tied category. As you rematch addresses, the addresses move automatically into the Matched category, so when you finish the process, that should be the only visible category; therefore, in the example above, it contains all 50 records at the end of the rematch process.
View geocoding results
The three categories displayed in the top portion of the Rematch pane provide a way for you to view and change the address currently active in the pane; only the active address can be rematched or matched.
Clicking the arrows on either side of the numbers showing which record is currently active selects the previous or next address within the selected category tab (Unmatched, Matched, or Tied).
The active address displays a default set of fields drawn from the attribute table of your geocoded feature class. When you interactively match an address, some values automatically generate as geocoding output, such as the values for Score, Side, Match_type, and Match_addr attributes. All the attributes from your original table of address data are also present in the geocoding results table. You can add or remove the fields from the table you want to view in the Rematch pane for each record by clicking the Select Fields button, and clicking the check boxes for the fields you want displayed.
The address candidates for the active address display in the lower portion of the pane. For each available candidate, a set of default fields always display: Matched, Address, Type, and Score. You can hide any of these fields using the Select Fields button. The Menu button allows you several options. You can zoom to view all candidates displayed on the map by clicking Menu and clicking Map All Suggestions . You can resort the candidates based on their default sort order by clicking Menu and clicking Default Sort Order . You can also select a set of addresses from your geocoded feature class to focus on in the Rematch Addresses pane by using queries. Click Menu , and click Predefined Queries to view a list of options for available preset queries that you can use on your table or for the option to create a custom query. If you make a selection by choosing one of the predefined queries or creating one of your own, the Rematch Addresses pane refreshes and will display only those records selected by your query rather than all the records in your table. Those records will still sort into the three available categories of Unmatched, Matched, and Tied.
You can also make selections manually in the attribute table for your geocoded feature class. Right-click the feature class in your Contents pane, and choose Attribute Table . Select rows or run queries directly on the table to update the records displayed in the Rematch Addresses pane. Editing the fields prefixed with IN_ will update the fields used to generate candidates for that record, and if Auto Apply is checked, the candidates for that record update accordingly.
Match and rematch addresses
All of the records in your geocoded feature class can be matched or rematched. You can match all records that failed to match, rematch matched records that you review and find to be unsuitable matches, or select the best match of a set of tied candidates. You can match the active address in the top portion of the Rematch Addresses pane to an address or location by using the bottom portion of the pane. If a suitable candidate displays automatically in the pane, you can match to it by clicking it and clicking Match . If a suitable candidate is not displayed, you have two options. If you are able to correct any fields for the original record by editing them in the top portion of the pane, the corrections may result in new candidates being generated. If you check the Auto Apply check box, all updates you make in the top portion of the pane will automatically update your table and re-geocode your record, which refreshes the candidates displayed in the bottom portion of the pane. If manually correcting the record still does not generate a suitable candidate, click a location on the map manually to generate a point, and match to the latitude and longitude of the location you clicked. To do this, click Pick from Map , and click the location on the map you want to match to. A new candidate with the latitude and longitude of that location generates in the candidate list in the bottom portion of the pane. You can then click that candidate and click Match .
Save your edits
When you finish matching unmatched addresses and reviewing and rematching matched or tied addresses, save your edits to make sure all of your changes are saved to your geocoded feature class. Both the updates to the table and to the points in the feature class will be saved. To save, click the Save Edits button in the lower portion of the Rematch Addresses pane. You can then close the pane.
