The Centrus GDT Data Set, which is based on Tele
Atlas Dynamap Streets, is designed for address level geocoding. When an address
level geocode is not available the GDT data set provides cascading accuracy at
the ZIP+4, ZIP+2, and ZIP Code centroid to return the highest level of geocode
for the address using Centrus GeoStan technology.
Centrus GDT Data utilizes the DYNAMAP/2000 street network database from Tele
Atlas North America 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 TANA street network ranges.
Dynamap/2000® contains more than 14 million addressed street segments. With
more than one million changes each month, this complete nationwide database
provides current and comprehensive street and address coverage for superior
geocoding performance.
-
Centrus GDT geocoding is based on the United States
Postal Service ZIP+4 database containing 40 million address ranges in 44,000
ZIP codes and addressed street segment records from the Tele Atlas North
America (TANA) street network database covering the United States and Puerto
Rico.
-
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.
-
The Centrus Tele Atlas Points Data
Set is available as an add-on to the Centrus
GDT Data Set for parcel and building level geocoding.
