Create Composite Address Locator (Geocoding)
Summary
Creates a composite address locator. A composite address locator consists of two or more individual address locators that allow addresses to be matched against the multiple address locators.
Usage
-
Prior to creating composite address locators, use the Create Address Locator tool to create participating address locators.
-
Spatial reference for a composite address locator is required. The spatial reference of the first participating address locator is used unless you specify a different output coordinate system in the tool's environment settings.
Syntax
| Parameter | Explanation | Data Type |
in_address_locators [[in_address_locator, name],...] |
The order of the participating address locators determines how candidates are searched and an address is matched. When you geocode a single address, the address will be matched against all participating address locators unless the locator is specified with a selection criterion. All the found candidates will be displayed based on the order of the listed participating address locators. If you geocode a table of addresses, addresses are matched automatically to the first best candidate found from the first participating address locators. If the address fails to match, it will fall back to the subsequent locator in the list. A reference name for each participating address locator is required. This is the name of the address locator referred to by the composite address locator. The name should contain no space or special symbols. The maximum length of the name is 14 characters. | Value Table |
in_field_map |
The mapping of input fields used by each participating address locator to the input fields of the composite address locator. | Field Mappings |
in_selection_criteria [in_address_locator, selection_criteria] (Optional) |
Selection criteria for each participating address locator. Only one selection criterion is supported for each participating address locator. Using selection criteria will disqualify participating address locators that do not meet the criteria on a particular address so that the geocoding process will be more efficient. Refer to the topic Creating a composite address locator to learn more about the use of selection criteria in the geocoding process. | Value Table |
out_composite_address_locator |
The composite address locator to create. | Address Locator |
Code Sample
The following Python window script demonstrates how to use the CreateCompositeAddressLocator function in immediate mode.
# Example 1: # Create a composite address locator using the StreetMap US Streets and Tutorial Atlanta locators. # Import system modules import arcpy from arcpy import env env.workspace = "C:/ArcTutor/Geocoding/atlanta.gdb" # Set local variables: US_Streets_locator = "C:/dm_stmap_dvd/streetmap_na/data/Street_Addresses_US" Atlanta_locator = Atlanta arcpy.CreateCompositeAddressLocator_geocoding( "Atlanta_locator Atlanta;US_Streets_locator US_Streets", "Address 'Street or Intersection' true true false 100 Text 0 0 ,First,#,Atlanta_locator,Address,0,0,US_Streets_locator,Street,0,0; City 'City or Placename' true true false 40 Text 0 0 ,First,#,Atlanta_locator,City,0,0,US_Streets_locator,City,0,0; State 'State' true true false 20 Text 0 0 ,First,#,Atlanta_locator,State,0,0,US_Streets_locator,State,0,0; Zip 'Zipcode' true true false 10 Text 0 0 ,First,#,Atlanta_locator,Zip,0,0,US_Streets_locator,ZIP,0,0", "Atlanta '\"City\" = 'Atlanta'';US_Streets #", Atlanta_Composite)
