Three address locators can be authored from the address information aggregated using the Community Addresses solution:
They leverage the features in the Community Address Information Model and can be built in ArcMap using your data. Once they have been authored, these locators can be used in ArcMap to locate places using common place-names, and rooftop address locations. The locators can also be published as geocoding services and used in many of the State and Local Government solution offerings.
Composite locator
A composite address locator consists of two or more individual address locators or geocode services. When addresses are geocoded against the composite address locator, they are automatically matched against each of the individual address locators and services. The composite address locator stores only references to the participating address locators and geocode services; it does not contain the actual address information, indexes, and data of the individual locators.
Some attributes of composite locators that may be of interest when working with state and local government data include the following:
- The composite locator consists of the other two provided locators. The order in which an address is evaluated against these locators can be adjusted in the properties of the composite locator.
- Composite locators can use an output spatial reference different from the participating address locators. The output spatial reference can be changed in the properties of the composite locator.
- Locators can be added or removed from the composite locator in the properties of the composite locator. For example, a United States National Grid (USNG)/Military Grid Reference System (MGRS) locator is included with ArcGIS and can be found at \ArcGIS\Desktop10.1\Locators. This locator can be added to the composite locator to provide additional search capabilities when working with the Emergency Management applications, for example.
Place-Name locator
This locator was created using the features in the SiteAddressPoint feature class (PLACENAME field) and uses the General—Gazetteer locator style.
Using this locator, you can search for places such as parks, schools, or other facilities by name rather than by address.
Site address locator
This locator was created using the features in the SiteAddressPoint feature class and uses the US Address—Single House locator style.
When created with the SiteAddressPoint feature class, this locator provides rooftop locations for addresses. Unlike many locators that use road centerlines and their address ranges to interpolate a location, this address locator will only find a location if a feature exists in the SiteAddressPoint layer for that address.
