Integrating Systems
with Accurate Addressing
Addressing--The Key to GIS
As GIS implementations mature, users throughout government and industry
are discovering the importance of accurate addressing. An address
ties a database record to a physical location and is often the only
common link between the multitude of databases and maps used in
business and government operations. Accurate addressing enables
efficient management and analysis of location-based information
within the GIS.
The address is truly the key to GIS.
To maximize the application of GIS in government, utilities, and
business environments, the creation of a master address file is
an essential first step. Initially most organizations begin this
process with many, often disparate databases with significantly
different address lists. For true systems integration, structure
number, street name, street direction, and suffix must be consistent
across databases and must be linked to the proper location on the
map.
To assist organizations in integrating their database systems and
mapping for location-based applications, Sewall is prepared to provide
address consulting and data modeling, address geocoding, address
validation and database loading, and master addess file creation.
ADDRESS
CONSULTING AND DATA MODELING
Sewall can determine the true addressing needs of an organization
and devise a methodology for implementation and long-term maintenance.
In addition, Sewall database experts can support the development
of a comprehensive addressing data model that will meet the needs
of an entire organization.
ADDRESS
GEOCODING
Geocoding creates the relationship between a point address and a
linear representation, such as road centerline, producing a logical
sequence of address ranges. Whether using existing source information
or collecting data in the field, Sewall analysts provide cost-effective
and accurate address geocoding services.
ADDRESS VALIDATION AND DATABASE LOADING
Sewall addressing technicians determine, rectify, and load the addresses
into a GIS database, using advanced software tools to correct misspelled
street names, bad parity, and non-linear roads; to identify missing
streets and street name aliases; to standardize abbreviations; and
to rectify incorrect house numbers.
MASTER
ADDRESS FILE CREATION
A master address file is critical to integrating disparate systems
within the GIS to support such location-based applications as asset
inventory for GASB34 compliance or E911 emergency dispatch for homeland
security. Not a trivial task, Sewall addressing analysts have the
expertise to authenticate and rectify addresses in all associated
data sets resulting in a single source for all addresses.
