U.S. Geocoding Databases

The U.S. geocoding databases contain the spatial data necessary to perform address standardization and geocoding. You must install at least one of these databases.

  • TomTom Geocoding—This database provides street segment data by TomTom, a third-party provider of spatial data, and postal data from the U.S. Postal Service.
  • HERE Geocoding—This database provides street segment data by HERE, a third-party provider of spatial data.

These databases use proprietary files called GSD files. For ZIP Code centroid matching, the file us.Z9 contains all the centroid info for all states and normally has a z9 extension.

Each geocoding database has an optional Statewide Intersections Index. The Statewide Intersection Index is designed to enable fast intersection identification on a statewide basis. For example, the Statewide Intersection Index will allow the database to search for "1st and Main St, CO" and return a list of possible matches in Colorado more quickly than searching the entire geocoding database for each instance of the intersection.

Note: To install the Global Geocoding Module databases on Windows Server 2008 you need administrator privileges.
  1. Make sure no applications are running.
  2. Download the database from the Pitney Bowes Software eStore using the link provided in the release announcement or welcome email.
  3. The database is downloaded as a zip file. Unzip the database before proceeding with the installation.
  4. Run DataSets.exe. The installation wizard guides you through the rest of the process.
    Note: You may install databases on a mapped drive, but performance will be affected since you will be accessing them on a network rather than accessing them locally.
  5. After you install the database files, use either the Global Geocoding Database Resource tool in the Management Console or the Global Geocoding CLI database commands to define the database as a resource. For more information, see the Administration Guide.
