Geocoding and address hygiene system employing point level and centerline data sets

摘要

A system (2) for geocoding and address hygiene includes a processing system (4) with an input and an output system (6) coupled to said processing system (4). A point level data set (8) is coupled to the processing system (4). A centerline data set (10) is coupled to the processing system (4). A cascade geocoding scoring and matching engine (12) is coupled to the processing system (4). A method (Figure 2) for processing two different types of geographic address data sets to establish candidate matched data includes entering (14) address data into the system and accessing a point level address data set. A determination (20) is made if the point level data set contains an exact match to the entered address data. Any exact address data match from the point level data set is output (22). Candidate address data matches from the point level data set are saved (24) when no exact match is determined as existing in the point level data set. The centerline address data set (10) is accessed and a determination is made of candidate address data matches from the centerline address data set. Candidate address data from both the point level data set and the centerline data set are scored and matched.
