Abstract:
In 1993, the
Maryland Department of Planning and the Maryland State Highway Administration
entered
into a Data Base Usage Agreement with Bell Atlantic and Data Chromatics, Inc.
to
develop an
enhanced street address map for Maryland.
Zip Code boundary area files were one
of the
products derived from this partnership. The resulting boundary area files were
intended
to improve the cartographic quality and accuracy of the zip code boundary area
files
derived from the U.S. Census Bureau's post 1990 Census TIGER\Line Files (based
on the
Census Bureau’s
zip code tabulation areas, ZCTAs).
Subsequent iterative improvements to the
Zip Code boundary area files have
been made using premise address information associated
with
mapped parcel records as provided in the Maryland Department of Planning’s MdProperty
View GIS tax map and parcel record
DVD product.
The resulting files are meant to
serve as a "good approximation” of zip codes as polygons
(which in
reality they are not) but are not official Zip Code maps and are not meant to
be a
substitute
for any products offered by the U.S. Postal Service, the official source for
zip
code
information. While there are no restrictions on their use we do recommend that
they are
best used
with MdProperty View and that MDP makes no guarantee
or warranty regarding the
files.
Zip Code information is provided on
a County-wide basis. County based files
are extracted from
a statewide
dataset. Polygons representing the full extent of the ZIP code are
provided. MDP also
has available a
statewide ZIP code file that is available upon request or via direct download
from
the MDP website.
