My Government Services and Geocoding

Question

We are considering using our own address locator for this application.  Is there any documentation on how to configure the address locator?  I have changed the url to our geocoding service, but I'm having trouble understanding the locate fields and other variables in config.js.  Thanks.

Thanks a lot Mike.  I have it working now.

Hi Jordan,

LocatorNameFields is used to connect the locator service to the app, because a call to a locator service in turn spawns calls to multiple types of locator.  When a response comes back from the locator, it can contain a response from each of the subsidiary locators; FieldName is the name of the attribute field with the name of subsidiary locator that provided a response. E.g., here is a snippet of a response    "candidates": [{
        "address": "971 Sylvan Cir, Naperville, IL, 60540",
        "location": {
            "x": -9810866.9852000009,
            "y": 5126375.4676999971
        },
        "score": 100,
        "attributes": {
            "Loc_name": "US_RoofTop",
            "Score": 100,
            "Match_addr": "971 Sylvan Cir, Naperville, IL, 60540",
            "House": "971",
            "Side": "L",
            "PreDir": "",
            "PreType": "",
            "StreetName": "Sylvan",
                :        :        :

Note the attribute "Loc_name" tells you that this candidate address came from the "US_RoofTop" subsidiary locator.

FieldValues holds the list of subsidiary locators whose results you want to display to your user.  In our try-it, e.g., the default address returns results from locators "US_RoofTop", "US_Streets", "US_StreetName", "US_Zipcode", and "US_CityState", but we only want to display results from "US_RoofTop" and "US_StreetName".

LocatorFields holds the name of the field that the locator service defines to accept a single-line address input parameter (i.e., one that doesn't have to be parsed by the app into street, city, etc., parameters). Our try-it uses the TA_Address_NA_10 service, which names this field "SingleLine". The newer World Geocoding Service also uses this name. (See also the ArcGIS API for JavaScript documentation for esri.tasks.Locator.addressToLocations().)

I am having the same issue.  I am using the 10.1 application.

I was able to implement my own address service within the Parks finder app without much of an issue however this one seems to be a bit different.

In the parks finder app there is only a space for the 'LocatorFileds' (similar to the second part below)

//Set locator name fields to search.
    LocatorNameFields: [{
        FieldName: 'Loc_name',
        FieldValues: ["CAN.PointAddress", "CAN.StreetAddress"]
}],

// Set Locator fields (fields to be used for searching).
        LocatorFields: "SingleLine",

Does anyone know what the script is looking for in the 'LocatorNameFields' (FieldName, FieldValue) vs. the 'LocatorFields'?

Thanks,

Jordan
