The Centrus NAVTEQ Data Set is designed for address
level geocoding. When an address level geocode is not available the NAVTEQ data
set provides cascading accuracy at the ZIP+4, ZIP+2, and ZIP Code level to
return the highest level of geocode for the address using Centrus GeoStan
technology.
Centrus NAVTEQ Data utilizes NAVTEQ’s NAVSTREETS™ street network database and
the US Postal Service ZIP+4 Address database to create a conflated Centrus
database that benefits from both the Postal address ranges and the NAVTEQ
street network ranges. This complete nationwide database provides current and
comprehensive street and address coverage for superior geocoding performance.
-
Centrus NAVTEQ geocoding is based on the United
States Postal Service ZIP+4 database containing 40 million address ranges in
44,000 ZIP codes covering the United States and U.S. protectorates.
-
Provides geocoding and address data, for CASS certified
processing, for use with all Centrus GeoStan based solutions.
-
The optional Statewide Intersection Index is designed
to enable fast intersection identification on a statewide basis as opposed to
the city/state or ZIP code basis. For example, the Statewide Intersection Index
will allow the database search for 1st and Main St, CO and return a list of
possible matches in Colorado more quickly than having to search the entire
Colorado database for each instance of the intersection.
