Data Options

The Data tab allows you to specify which databases to use in reverse geocoding. Databases contain the address and geocode data necessary to determine the address for a given point. The following table lists the options available for specifying the search order of databases.

Option Name

Description

Override the default database search list

Specifies whether to use the database search list specified in the Management Console. If you choose to override the default database search list you may change the search order of the databases in the Database search list field. You may also remove databases from the search list.

If you override the default database search list, changes to the database resources will not be reflected in the database search list, which may cause geocoding to fail. However, if you do not override the default database search order, any changes to the database resources will be automatically reflected by the geocoder.

Database search list

The name of one or more database resources to use in the search process. Use the database name specified in the Management Console.

You can specify multiple database resources. If you specify more than one database, list them in order of preference.

The order of the databases has an effect when there are close match candidates from different databases. The close matches that are returned come from the database that is first in the search list. Close matches from lower ranked databases are demoted to non-close matches.

You can also use the order of the databases to perform fallback processing if you have an both an address point database and a street-level database installed for the country. List the address point database first and the street database second. If the address cannot be geocoded to the address point level, the geocoder will attempt to geocode it to the street level.
