a phrase denoting a location.

the technique of linking data from separate files by means of a
common attribute, the street address. See also Geocoding.

the range of house numbers along a specific street segment; in
address matching an X,Y location is interpolated along a street centerline based on the
address range values.

a set of rules for assigning addresses along a transportation
network (streets, freeways, railroads); addresses in this context may be almost
anything that identifies a point along a segment: house numbers, callbox numbers,
mileposts, block/lot numbers, and/or post office box numbers.

house numbering system in which house numbers increase
away from an origin in a cardinal direction (North, South, East, West); the line that
separates north from south numbers is called a baseline; a meridian separates
east-west numbers; the orientation of the system may be rotated east or west of due
north; if such rotation is substantial, house numbers may be designated SW, SE, NW or
NE.

situation in which the same street segment carries house numbers
from two different house numbering systems.

any of a number of geographic location systems, including street address,
area code, ZIP and ZIP + 4, census tract, tax parcel, and latitude/longitude
coordinates.

the process of assigning a geographic location from an address record.
See also Address Matching.

a convention for the assignment of addresses to buildings,
residences and occupancies.

a convention for using one or more house numbering
systems at a particular place, such as a community or city; for example, a scheme may
employ one numbering system for east-west streets, and another system for
north-south streets in the same community.

addressing system in which numbers increase in a linear fashion
away from a specified Origin (e.g., mileposts along a highway).

the inventory of a particular phenomena (e.g., Best Buy
customers) by address; also referred to as an application database.

house numbering system in which houses are numbered in the order
that residences are built.

house numbering system "rule" specifying that opposite sides of the
street have all odd or all even numbers.

an interactive process in which addresses are made to match the
records in the spatial address file; this process involves changing street names, street
types, etc., and also includes matching to a more general geocode (zip or zip + 4)
rather than to a street address.

site specific, or location address (as opposed to a mailing address,
which does not necessarily correspond with the site location).

line representing the center of a street segment; a digital street
centerline file is used in conjunction with a master address file to assign an address to a
specific geographic location; spatial discrepancies in the street centerline file may lead
to erroneous address matching (or no match at all); it is therefore critical that the
centerline coverage be as accurate as possible.

the non-name components of an address, including street type
(Avenue, Road, Boulevard, etc.) and street direction (North, South, East, West).

the legal name of a particular street , generally assigned by a municipal or
county agency.

an area (generally represented as a centroid) corresponding to an
individual property; the use of tax parcels in geocoding allows a one-to-one match
between address records and unique geographic locations; the use of other geocodes
(census tracts, wire centers, ZIP and ZIP + 4 regions) will result in the assignment of
multiple address records to the same centroid location.

the basic geographic unit used in the telecommunications industry; a
subdivision of a telephone area code, identified by the first three digits of a phone
number (e.g., 777-1234).

a system of 9-digit codes that identifies specific
delivery points; the first five digits identify the individual post office or metropolitan area
delivery station associated with the address.

ZIP designation (e.g., 66044-35) identifying a sector or geographic portion of a
zone; it can also indicate a portion of a rural route or part of a P.O. Box section.

as defined by Geographic Data Technology, Inc., the point that is the
average of all ZIP + 4 centroids in the ZIP + 2 sector; because the ZIP + 2 centroid
reflects the distribution of ZIP + 4 centroids, it is a good indicator of address
concentration.

ZIP designation (e.g., 66045-3545) identifying a specific block face (an
average of six to ten houses), apartment house bank of boxes, firm, building or other
specific delivery location; there are over 50,000 ZIP + 4 locations in Richland and
Lexington Counties in South Carolina.
 
 

 

as defined by Geographic Data Technology, Inc., the point

corresponding to the house number which is closest to the mid-address of the ZIP + 4
address range.
