TITLE: 2010 U.S. CENSUS URBAN AREAS AND CLUSTERS IN FLORIDA

Geodataset Name:       UA2010
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Polygon
Feature Count:         104
GENERAL DESCRIPTION:
This dataset contains 2010 Urban Area boundaries derived from TIGER/Line Files. After each decennial census, the Census Bureau delineates urban areas that represent densely developed territory, encompassing residential, commercial, and other nonresidential urban land uses. In general, this territory consists of areas of high population density and urban land use resulting in a representation of the "urban footprint." There are two types of urban areas: urbanized areas (UAs) that contain 50,000 or more people and urban clusters (UCs) that contain at least 2,500 people, but fewer than 50,000 people (except in the U.S. Virgin Islands and Guam which each contain urban clusters with populations greater than 50,000). Each urban area is identified by a 5-character numeric census code that may contain leading zeroes.

USER NOTES:
The Census Bureau performed automated tests to ensure logical consistency and 
limits of shapefiles.  Segments making up the outer and inner boundaries of a 
polygon tie end-to-end to completely enclose the area.  All polygons are tested for 
closure.
The Census Bureau uses its internally developed geographic update system to 
enhance and modify spatial and attribute data in the Census MAF/TIGER 
database.  Standard geographic codes, such as FIPS codes for states, counties, 
municipalities, county subdivisions, places, American Indian/Alaska Native/Native 
Hawaiian areas, and congressional districts are used when encoding spatial 
entities.  The Census Bureau performed spatial data tests for logical consistency of 
the codes during the compilation of the original Census MAF/TIGER database files.  
Most of the codes for geographic entities except states, counties, urban areas, Core 
Based Statistical Areas (CBSAs), American Indian Areas (AIAs), and congressional 
districts were provided to the Census Bureau by the USGS, the agency responsible 
for maintaining FIPS 55.  Feature attribute information has been examined but has 
not been fully tested for consistency.
For the TIGER/Line Shapefiles, the Point and Vector Object Count for the G-
polygon SDTS Point and Vector Object Type reflects the number of records in the 
shapefile attribute table.  For multi-polygon features, only one attribute record exists 
for each multi-polygon rather than one attribute record per individual G-polygon 
component of the multi-polygon feature.  TIGER/Line Shapefile multi-polygons are 
an exception to the G-polygon object type classification.  Therefore, when multi-
polygons exist in a shapefile, the object count will be less than the actual number of 
G-polygons.
Data completeness of the TIGER/Line Shapefiles reflects the contents of the 
Census MAF/TIGER database at the time the TIGER/Line Shapefiles were 
created.
GeoPlan relied on the integrity of the attribute information within
the original data.
The TIGER/Line Files are shapefiles and related database files (.dbf) that are an 
extract of selected geographic and cartographic information from the U.S. Census 
Bureau's Master Address File / Topologically Integrated Geographic Encoding and 
Referencing (MAF/TIGER) Database (MTDB).  The MTDB represents a seamless 
national file with no overlaps or gaps between parts, however, each TIGER/Line 
File is designed to stand alone as an independent data set, or they can be 
combined to cover the entire nation.

In order for others to use the information in the Census MAF/TIGER database in a 
geographic information system (GIS) or for other geographic applications, the 
Census Bureau releases to the public extracts of the database in the form of 
TIGER/Line Shapefiles.

The boundary information in the TIGER/Line Shapefiles are for statistical data 
collection and tabulation purposes only; their depiction and designation for statistical 
purposes does not constitute a determination of jurisdictional authority or rights of 
ownership or entitlement and they are not legal land descriptions. Coordinates in the 
TIGER/Line shapefiles have six implied decimal places, but the positional accuracy 
of these coordinates is not as great as the six decimal places suggest.

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.

Furthermore, the GIS data available in the FGDL are provided 'as is'.

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:
TIGER/Line Shapefiles are extracted from the Census MAF/TIGER database by 
nation, state, county, and entity.  Census MAF/TIGER data for all of the 
aforementioned geographic entities are then distributed among the shapefiles each 
containing attributes for line, polygon, or landmark geographic data.

GeoPlan downloaded this data on April 4th, 2012 from the following link: ftp://ftp2.census.gov/geo/tiger/TIGER2010/UA/2010/ When downloaded the data was in shapefile format and was projected in Decimal Degrees NAD83. The shapefile was projected to Albers - HARN. The following qaqc task were completed: -Selected out Florida records -Upcased on text fields -Added DESCRIPT field based on NAME field -Added FGDLAQDATE based on date data was downloaded from source. -Changed name from tl_2010_us_uac10.shp to ua2010.shp Process Date: 20120417
