The Value Method field in the DynamicValue table defines the actions that occur when the Attribute Assistant is enabled and features are modified or created in ArcMap. Four fields in the DynamicValue table (Value Method, Table Name, Field Name, and Value Info) must be configured to use an Attribute Assistant method. The remaining fields define when the Attribute Assistant method should be applied.
The following seven Attribute Assistant methods can be configured in your DynamicValue table:
| Method | Description |
| Get Address From Centerline | Extracts address information from the closest point on a road. It is similar to a reverse geocode, but a locator service is not used. |
| Get Address Using ArcGIS Service | Performs a reverse geocode using a specified ArcGIS service. |
| Get Address Using Geocoder | Performs a reverse geocode using a geocoder. |
| Latitude | Stores the y-coordinate value projected to WGS84 decimal degrees. |
| Longitude | Stores the x-coordinate value projected to WGS84 decimal degrees. |
| X Coordinate | Calculates the x-coordinate of a feature in database units. |
| Y Coordinate | Calculates the y-coordinate of a feature in database units. |
Get Address From Centerline
Extracts address information from the closest point on a road. It is similar to a reverse geocode, but a locator service is not used.
To configure this method, populate the following in the DynamicValue table:
| Table Name | Field Name | Value Method | Value Info |
| Feature class | Field to which the address will be written | GET_ADDRESS_FROM_CENTERLINE | Roads|Source|{Neighborhood} |
This rule always searches the feature class, not the feature layer.
Parameters
The method parameters are as follows:
| Parameter | Value | Description |
| Roads | Feature class | Road centerlines feature class. |
| Source | String | Addressing information fields in the format: Road Name, To Left, To Right, From Left, From Right. |
| Neighborhood (Optional) | Value | Maximum distance to search for nearest feature. If not specified, only intersecting features are used. |
Examples
Stores the address from a five foot search of the RoadCenterline layer:
- Table Name: ProposedSites
- Field Name: ADDRESS
- Value Info: RoadCenterline|ROADNAME,TOLEFT,TORIGHT,FROMLEFT,FROMRIGHT|5
Get Address Using ArcGIS Service
Performs a reverse geocode using a specified ArcGIS service.
To configure this method, populate the following in the DynamicValue table:
| Table Name | Field Name | Value Method | Value Info |
| Feature class | Field to which the address will be written | GET_ADDRESS_USING_ARCGIS_SERVICE | {URL to Locator}|{WKID} |
This rule can only be configured on String fields.
Parameters
The method parameters are as follows:
| Parameter | Value | Description |
| URL to Locator (Optional) | <Null> (Default) |
