You can create these fields and assign the values in your reference data. The following four elements define the extent of the feature. The ArcGIS Online World Geocoding Service, for example, contains these predefined values. If a locator is specified with predefined x,y minimums and maximums for each feature from the reference data, the Zoom To command for the found locations in the Find dialog box, Geocoding toolbar, or Interactive Rematch dialog box will use these values from the locator as the extent to which to zoom to.

You can use Esri StreetMap data, data from your own organization, or data from other data providers. You have a few options for acquiring reference data for address locator styles. Each address locator style has specific requirements for the reference data that it can use to match addresses. These address locator styles cover some of the most common address formats. Specifying reference data containing geometry and address elements for each featureĪrcGIS comes with several predefined address locator styles that you can use to create address locators. Customized locator styles can also be developed for finding locations based on specific locational systems, such as national grid coordinates, GPS positions, or borehole identifiers.
There are other locator styles that can be used for finding places, landmarks, ZIP Codes, or city names. Some styles require that the address elements be separated into individual fields in a table.Īddress locator styles are not limited to street address geocoding. Each address locator style requires that the address information being searched is presented based on some guidelines. The following illustration shows how the address locator style, as a framework for the address locator, directs various functions for the entire geocoding process: Searching for specific address elementsĪddresses consist of specific components referred to as address elements. The address locator also directs the geocoding engine to perform parsing the address, matching of an address against the found candidate, and reverse geocoding an address. Once created, an address locator contains the geocoding properties and parameters that are used in the geocoding processes, components that direct how an address is parsed, a snapshot of the address attributes in the reference data, and the criteria for performing a geocoding search. An address locator is created based on a specific locator style. The address locator style is the template for an address locator.
