Address auditing using GIS

Blog_AddressauditingusingGIS.jpg

When the Village of Norridge needs to send out a mass mailing to its
residents, the Village typically uses the addresses found in the water
billing database. After each mailing, the Village typically receives a
small amount of letters deemed undeliverable. In an effort to eliminate
the undeliverable letters, the Village decided to go through the
database and make sure all the addresses in the village were accounted
for. They decided to map out the water addresses using a GIS process
called geocoding.

Geocoding is a process of taking a list of addresses and then mapping
them in GIS using an existing addresses database as the reference data.
The list of addresses from the water billing database were first
mapped out against the existing GIS address database. This process
generated a list of all the addresses from the water billing database
that did not match any address in the GIS database. With this list
created, the village went out and field verified the addresses in
question, as well as any returned mail, to determine the actual
addresses. With all the errors corrected, a final master address
database was created that could be used for a number of different
mailings, such as billings, vehicle sticker notifications, and voting
information. By having a master address list, the village is able to
send out mass mailings with a minimal amount of returned mail, in turn
cutting down on wasted time, envelopes, and postage.
