THE CALL COMES IN Continued from page 49 and passes unmatched addresses from each locator to the next. This composite address locator will geocode using Parcel Centroids first, then City Streets, and finally TIGER Streets. 1. Right-click the \Lakewood\SHPFiles\ StatePlane folder and specify Composite Address Locator. 2. Using Table 3, name this locator Composite_Parcel_ Street_TIGER and add participating locators in order: 1_, 2_, and 3_. These numeric name prefixes will be useful soon. 3. Once all three are loaded, perform the next step. It is a performance tip. On the right side of the New Composite Address Locator wizard, find the Input Address Fields area. Next to The field containing window, click the Add button and specify Address as the primary field. Set its recognized name to only Address2. By specifying only Address2, the composite address locator will target only standardized data and ignore other Address fields. Typically reference datasets can also contain a primitive Address field. 4. Keep all Participating Address Locators checked; select each one and individually set its Input Mappings field to Address. Use any individual address locator to calculate the output spatial reference. After setting the spatial reference and all three Input Mappings, the OK button should become active. If it does not, review the setting. Click OK to build the composite address locator. Now it is time to geocode all 6,976 incidents. Close ArcCatalog and reopen the Lakewood map document in ArcMap. Task 4: Geocoding Incidents Now, after setting some parameters for the composite address locator, it will automatically geocode all the incidents. 1. In ArcMap, load the Geocoding toolbar, if necessary, and click the Address Locator Manager button. Navi- Use the three individual address locators to create a composite address locator. Keep all Participating Address Locators checked and select each one and individually set its Input Mappings field to ADDRESS2. www.esri.com 50 ArcUser Spring 2010
