How the Geocoder transform works
The Geocoder transform uses geographic coordinates expressed as latitude and longitude, addresses, and point-of-interest (POI) data. Using the transform, you can append addresses, latitude and longitude, census data, and other information to your data.
Based on mapped input fields, the Geocoder transform has three modes of geocode processing:
- Address geocoding
- Reverse geocoding
- POI textual search
In general, the transform uses geocoding directories to calculate latitude and longitude values for a house by interpolating between a beginning and ending point of a line segment where the line segment represents a range of houses. The latitude and longitude values may be slightly offset from the exact location from where the house actually exists.
The Geocoder transform also supports geocoding parcel directories, which contain the most precise and accurate latitude and longitude values available for addresses, depending on the available country data. Geocoding parcel data is stored as points, so rather than getting you near the house, it takes you to the exact door.
Typically, the Geocoder transform is used in conjunction with the Global Address Cleanse or USA Regulatory Address Cleanse transform.
The Geocoder transform is flexible enough to accept new country directory data immediately after the directory data is released. There is no need to wait for the next SAP Data Services release to begin using new country directory data. At the time of this publication, the Geocoder transform uses US, Canadian, French, German, and UK directory data. Check with your sales representative for a list of the most current country directories available.
