Geodataset Type:       SHAPEFILE
Geodataset Feature:    Polygon
Feature Count:         40
GENERAL DESCRIPTION:
An urbanized area (UA) consists of at least one central place and the adjacent densely settled surrounding territory that together have a minimum population of 50,000 people. The densely settled surrounding territory generally consists of an area with continuous residential development and a general overall population density of at least 1,000 people per square mile.

USER NOTES:
This data is provided 'as is'. GeoPlan relied on the integrity
of the original data layer's topology
This data is provided 'as is' by GeoPlan and is complete to our
knowledge.
GeoPlan relied on the integrity of the attribute information within
the original data.
In order to maintain a current geographic database from which to extract 
the TIGER/Line files, the U.S. Census Bureau uses various internal and 
external procedures to update the Census TIGER data base. While it has 
made a reasonable and systematic attempt to gather the most recent 
information available about the features this file portrays, the U.S. Census 
Bureau cautions users that the files are no more complete than the source 
documents used in their compilation, the vintage of those source documents, 
and the translation of the information on those source documents.

The TIGER/Line files use a single field to identify places that are legal 
entities, and places that are statistical entities. The FIPS place code 
uniquely identifies a place within a state. If place names are duplicated 
within a state and they represent distinctly different areas, a separate 
code is assigned to each place name alphabetically by primary county 
in which each place is located, or if both places are in the same county, 
alphabetically by their legal descriptions (for example, "city" before "village").

The data was created to serve as base information for use in GIS systems 
for a variety of planning and analytical purposes.

THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED

MODIFYING, CONTRIBUTING OR DISTRIBUTING THE MATERIALS.

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY:
SOURCE DATA PROCESSING PROCEDURES:

The TIGER/Line files are extracts, from the Census TIGER (Topologically 
Integrated Geographic Encoding and Referencing) data base, of selected 
geographic and cartographic information. The U.S. Census Bureau s Census 
TIGER System automates the mapping and related geographic activities 
required to support the decennial census and sample survey programs of the 
U.S. Census Bureau starting with the 1990 decennial census. They include 
files for all counties and statistically equivalent entities in the United States 
and Puerto Rico.

The initial sources used to create the Census TIGER data base were the 
USGS 1:100,000-scale Digital Line Graph (DLG), USGS 1:24,000-scale 
quadrangles, the U.S. Census Bureau s 1980 geographic base files (GBF/ DIME-Files), 
and a variety of miscellaneous maps for selected areas outside the contiguous 
48 states. The DLG coverage is extensive, albeit of variable currency, and 
comprises most of the rural, small city, and suburban area of the TIGER/Line files. 
GBF/DIME-File coverage areas were updated through 1987 with the manual 
translation of features from the most recent aerial photography available to the 
U.S. Census Bureau.

The U.S. Census Bureau has added to the Census TIGER data base the 
enumerator updates compiled during the Census 2000 census operations. 
The updates came from map annotations made by enumerators as they 
attempted to locate living quarters by traversing every street feature in their 
assignment area. The U.S. Census Bureau digitized the enumerator updates 
directly into the Census TIGER data base without geodetic controls or the 
use of aerial photography to confirm the features  locational accuracy.

The U.S. Census Bureau also made other corrections and updates to the 
Census TIGER data base supplied by local participants in various U.S. 
Census Bureau programs. Local updates originated from map reviews by 
local government officials or their liaisons and local participants in U.S. 
Census Bureau programs. Maps were sent participants for use in various 
census programs, and some maps were returned with update annotations 
and corrections. The U.S. Census Bureau generally added the updates to 
the Census TIGER data base without extensive checks. Changes made by 
local officials do not have geodetic control or coordinate system.
