|Modules and Stages|
The GeoConfidence Module is used to determine the probability that an address or street intersection is within a given area. The module takes an address or intersection's location (determined by Geocode US Address), converts that location to a point, line, or polygon (depending on the precision of the match), then compares that shape with a database of known shapes to see if the two overlap, and the percentage overlap. For example, you could use the GeoConfidence Module to make decisions on a flood zone rating based on how much overlap there is between an address's location and the flood zone data. Anything greater than a 95% overlap with a 100-year flood zone may indicate that the address is in the flood zone. Conversely, anything less than 95% could cause your business process to send the address to exception processing that might include a manual review.
An address or intersection can be geocoded to a point, an address along a street segment (an array of street segment points), ZIP + 4 centroid, ZIP + 2 centroid, or ZIP Code centroid (polygons). You can use these shapes (points, lines, or polygons) to compare with other shapes to determine overlap, which can be used to determine a risk or probability.
Different geoconfidence polygons are generated depending on the GeoConfidence result returned by the Enterprise Geocoding Module. Refer to the Enterprise Geocoding Module documentation for more information about the GeoConfidence information returned by the Enterprise Geocoding Module.
The GeoConfidence Module supports U.S. locations only.
