Geocoding services ("geocoders") convert between addresses and spatial data. Converting an address to spatial data enables the address to be shown on the map. This is called "forward geocoding". Converting from spatial data (a geographic location) to an address is called "reverse geocoding".
In order for a site's viewers to do operations that involve geocoding, you must configure at least one geocoding service in the site. Essentials supports unsecured and secured ArcGIS geocoding services, and the Bing Maps geocoding service.
After you have added a geocoding service to a site, you might need to configure additional settings. This depends on what type of viewer you are using and which geocoding-dependent features you configure.
Additional geocoding service settings (other settings are omitted)
The settings are summarized in the table below. In the table, the geocoding service settings are identified by number. The numbers relate to the screen capture above.
To use the table, first look in the Feature column to find the feature that you want to configure. Now read across the row for that feature to find out which settings to configure. In addition to configuring the geocoding settings, you must configure the feature itself. Follow the link given in the Feature column to configure the feature.
The table uses the following values:
Yes: You must configure the settings that say Yes for that feature.
Optional: Settings that are Optional allow you to configure optional aspects of that feature. You do not need to configure Optional settings.
No Effect: If you configure a setting that has No effect, the setting will not have any effect on the feature (it might affect other features, if you configure more than one of the features listed in the table). For example, configuring a Display Name for Global Search has no effect. You do not need to configure settings that have no effect, but there is no harm if you do.
For information about what the individual settings do, see Configuration Settings for ArcGIS Geocoding Services and Configuration Settings for the Bing Maps Geocoding Service .

Display Name: The name that is used to refer to this geocoding service.
Choose a display name that end users understand.
Service URL: The geocoding service's URL. Features that use this geocoding service send geocode requests to this URL.
Default Batch Geocoder: Makes this geocoder the default for batch geocoding. This setting only applies to one geocoder at any time.
Default Reverse Geocoder: Makes this geocoder the default for reverse geocoding. Reverse geocoding is the process of determining the address of a given map point. This setting only applies to one geocoder at any time.
Icon URI: Configures a custom icon for this geocoding service.
Feature Zoom Scale: The scale to zoom to when clicking a geocoding result.
Authentication Settings: If the geocoding service is secured, select the authentication method for Essentials to use when connecting to the service.
Web Tier (default or anonymous credentials): Select this option if:
The service is secured using Integrated Windows Authentication and you want Essentials to authenticate as the application pool user.
or
The service is not secured.
Web Tier (configured credentials): Select this option if:
The service is secured using basic or digest authentication.
or
The service is secured using Integrated Windows Authentication and you want to configure the credentials for Essentials to use when authenticating.
In the Username and Password text fields, enter the credentials that you want Essentials to use.
Token Security (by user): Select this option if the service is secured using token security.
In the Username and Password boxes, type the credentials that you want Essentials to use when authenticating. If you have changed the location where tokens are issued, type the URL of the location in the Token URL box.
By default, Essentials assumes the token duration of all your ArcGIS services is 60 minutes, which is the ArcGIS default. However, if the token duration of any of your ArcGIS services is shorter, you must specify the token duration in Essentials. To specify the token duration:
Open the Essentials web.config file.
The Essentials web.config file is located in {GE_HOME}\REST\Web.config.
In the appSettings element, add a new add element.
Add a key attribute to appSettings and set it to ArcGisRestMapServiceBase.MaximumTokenDuration.
Add a value attribute to appSettings and set it to the maximum token duration in minutes.
For example, to set the maximum token duration to 20 minutes:
<add key="ArcGisRestMapServiceBase.MaximumTokenDuration" value="20" />.
Token Security (explicit tokens): In the Server Token box, type or paste the long-lived server token that Essentials will use to authenticate. You can also optionally configure a long-lived client token.
Select this option if the service is secured using token security and you want to use long-lived tokens. This method stores the token(s) in the site.
Include in Global Search: When this checkbox is selected, the geocoding service can be searched in Global Search operations.
Global Search Key: The geocode service field to use when a value is entered in Global Search. The default is SingleLine. This setting is only available when the Include in Global Search checkbox is selected. Note that when the global search key is SingleLine, parameters configured for the Geocoding Service are ignored when sending Global Search queries. To use additional parameters, select a global search key other than SingleLine.
Parameters: Use this table to configure the geocoding service to be used by features that perform forward geocoding.
Parameter: (for information only) The geocoding service's Address Fields.
Display Name: (used by Address Search) The label to display beside the box where the user enters the value for this parameter. For example, if the geocoding service has a Zip field, you could set the display name to "Zip/Postal Code".
Value: An optional setting used by Global Search, Address Search, and Batch Geocoding. The value to search for (Global Search) or to use in geocoding (Address Search, Batch Geocoding). HTML5 viewers only use Value if the end user does not specify a value. Legacy Silverlight viewers only use Value if the Required checkbox is selected and the end user does not specify a value.
Required (Silverlight viewers only): When this checkbox is selected, the parameter must have a value before an Address Search or Batch Geocode can be done. The value can either come from the configuration (the parameter's Value setting) or from the end user. If the end user specifies a value, it overrides the value that is configured in the site. This setting is optional.
Visible: When this checkbox is selected, the Address Search panel has a text box for the user to enter a value.
