Scan/US Geocoder:
Affordable...Accurate...Accessible...your stand-alone solution for address-related spatial
data. Geocoding is the process of
converting geographic information into latitude/longitude
coordinate pairs. For example, 123 Main Street, in Anytown,
USA, is geographic information. But that information must be
transformed into numeric values (“coordinates”) before the
address can be rendered on a map. Geocoding parses the
address components, and matches them to a database of
coordinate information. These coordinates are required by
mapping software, which displays the location.
As a mapping application,
Scan/US for Windows uses a “virtual” landscape to display
different geographic features and locations. Scan/US
composes this landscape from a combination of polygons,
lines & points. Each polygon, line and point is defined by a
sequence of numeric values, the “coordinates” or “coordinate
pairs.”
Each coordinate consists of
2 numeric values that represent distance from the Equator
(the “Latitude”) and the Prime Meridian (the “Longitude”).
When a single coordinate pair is displayed on the landscape,
Scan/US draws a “point,” indicating a fixed location.
Scan/US can also connect a series of coordinates
sequentially to form lines. And finally, coordinates linked
sequentially, including a joining of the last coordinate
pair and the initial coordinate pair, form “polygons,” or
“enclosed objects.”
Do you need a Geocoder?
If you
have Scan/US, you already have a geocoder! Each time you use
the “Find Address”, “Site Express”, or “Go To...” utilities,
you use some form of the Scan/US Geocoder. The obvious
limitation is that you must enter each address individually.
When it is impractical to
enter large numbers of addresses by hand, you should
consider a “batch” geocoding option. Batch geocoding allows
you to load a database of addresses, process the database in
an unattended mode, and append latitude/longitude
coordinates to each record as additional data. Then all
addresses can be displayed.
And with Scan/US Site
Factory, you can run reports, directly from your address
files, in an unattended batch operation! Or select specific
demographic variables, and produce a spreadsheet database
with all of your addresses organized for easy ranking and
sorting on those variables that matter most to your
analysis!
Address Standardization.
Scan/US Geocoder will process your file (with an unlimited
number of addresses anywhere in the U.S.) standardizing
addresses to U.S. postal regulations, and assign Latitude
and Longitude coordinates and geographic IDs, all in a
single pass.
Without coordinates, your
addresses cannot be displayed as points on a map! Scan/US
Geocoder assigns coordinates with precision, based on the
exact street address or a ZIP+4 centroid—precise enough to
show your locations on the correct side of the street!
Why is Scan/US Geocoder the
most accurate? Scan/US Geocoder references both the latest U.S.
Census Bureau’s TIGER street database and a 55 million
record ZIP+4 database to look up your addresses and assign
coordinates to them. When a matching address is found in the
TIGER street database, its Lat/Long coordinate is assigned
to your address. When a match is not found, Scan/US Geocoder
assigns a coordinate from the ZIP+4 database, or as a last
resort, a 5-digit ZIP centroid.
You get the best match rates
from Scan/US Geocoder because the addresses in its street
database have been standardized to U.S. Postal Service’s
guidelines. During processing, your addresses are also
standardized to those same guidelines—minimizing the effect
of incorrect or incomplete addresses and misspellings—to
ensure that the best matching addresses are found in the
reference databases.
