Introduction - global_geocoding - 23.1

This guide provides information on using Spectrum Global Geocoding. Spectrum Global Geocoding integrates geocoding support for over 150 countries and includes the following stages:

• Geocode Service: performs forward geocoding using input addresses and returning location data and other information.
• Reverse Geocode Service: performs reverse geocoding using input coordinates and returns address information that is the best match for that point.
• Interactive Geocode Service: suggests addresses and place names as you type.
• Key Lookup Service: returns geocoded candidates when given a unique key. It is a more efficient method than matching with an address, as the key is unique to that address. Spectrum Global Geocoding supports the PreciselyID unique identifier for US data and the G-NAF key for AUS data.

The Spectrum Global Geocoding is delivered as a Spectrum Technology Platform module and can be built into stages just like any other component. Spectrum Technology Platform must already be installed.

These stages provide options that allow control of the geocoding dataset resources, searching and matching criteria, and other preferences in a graphical interface.

After installing and deploying the Spectrum Global Geocoding, you can use Management Console to explore all the capabilities and see candidate results. You can also include GGM stages in your dataflow in Enterprise Designer.

You can use additional features and preferences through the REST API. See Global Geocoding API.

The Reverse Geocode Service takes latitude/longitude coordinates for a point as input and returns address information that is the best match for that point.

The Interactive Geocode Service, when built into an application, will provide type-ahead capabilities. Only the first few characters of a place or address will yield match candidates. With additional typing, more specific information is revealed and the results are refined to display more relevant candidates. Candidates include the full address, placename category and subcategory, and indicate the distance from the origin if the distance is provided in the input.
