Setting Address Locator properties using ArcObjects

GeoDecisionsEDN9GannettFleming — Wed, 17 Sep 2014 16:05:40 GMT

I am creating an Address Locator using ArcObjects and assigning properties to it, primarily through the IGeocodingProperties2 interface. I cannot find how to set two properties - “write locator specific output fields” and “write display extent output fields" - these do not seem to be exposed by this or any other interface

In the ArcMap GUI, you can set them under Address Locator -> Properties -> Outputs, as shown in the image below

My locator creation code is straightforward. It expects the feature dataset (featureDataset below) and featureclass (featureClass below) where reference data is stored - to be already known:

IWorkspace workspace = featureDataset.Workspace;

// Open the database locator workspace for the ArcSDE workspace.

System.Object obj = Activator.CreateInstance(Type.GetTypeFromProgID("esriLocation.LocatorManager"));

ILocatorManager2 locatorManager2 = obj as ILocatorManager2;

ILocatorWorkspace locatorWorkspace = locatorManager2.GetLocatorWorkspace(workspace);

// Get the Locator Style from the client workspace

ILocatorWorkspace clientLocatorWorkspace = locatorManager2.GetLocatorWorkspaceFromPath("");

ILocatorStyle locatorStyle = clientLocatorWorkspace.GetLocatorStyle("US Address - Dual Ranges");

// Given the featureclass holding the reference data.

IDataset dataset = (IDataset) featureClass;

IReferenceDataTables referenceDataTables = (IReferenceDataTables) locatorStyle;

IEnumReferenceDataTable enumReferenceDataTable = referenceDataTables.Tables;

enumReferenceDataTable.Reset();

IReferenceDataTable referenceDataTable = enumReferenceDataTable.Next();

IReferenceDataTableEdit referenceDataTableEdit = (IReferenceDataTableEdit) referenceDataTable;

referenceDataTableEdit.Name_2 = (ITableName) dataset.FullName;

// Store the locator if the reference data is properly specified.

ILocator locator = null;

if (referenceDataTables.HasEnoughInfo)

{

string targetLocatorNameString = "Loc01";

locator = locatorWorkspace.AddLocator(targetLocatorNameString, (ILocator)locatorStyle, "", null);

// Set the custom geocoding properties.

//Write locator-specific output fields : Yes, Return display extent output fields : Yes

IGeocodingProperties2 geocodingProperties2 = locator as IGeocodingProperties2;

geocodingProperties2.AddXYCoordsToMatchFields = true;

geocodingProperties2.MinimumCandidateScore = 10;

geocodingProperties2.SideOffset = 10;

geocodingProperties2.EndOffset = 10;

locatorWorkspace.UpdateLocator(locator);

}

Any code samples would help.

Thanks!

You would do it in the following way if you want to do it at runtime:

ILocatorImpl locatorImpl = locator as ILocatorImpl;

IPropertySet locatorProperties = locatorImpl.Properties;

locatorProperties.SetProperty("WriteDisplayExtentFields", "True");

locatorProperties.SetProperty("WriteLocatorSpecificFields", "True");

locatorImpl.Properties = locatorProperties;

If you want to do it to the locator and keep them updated, you can modify the .loc file directly using a text ediitor.
