Geodataset Name:       CENZCTA2010_FEB12
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Polygon
Feature Count:         983
GENERAL DESCRIPTION:
This dataset contains the 2011 Florida zip code tabulation areas (ZCTAs). 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). ZIP Code Tabulation Areas (ZCTAs) are approximate area representations of U.S. Postal Service (USPS) ZIP Code service areas that the Census Bureau creates to present statistical data from Census 2010. Data users should not use ZCTAs to identify the official USPS ZIP Code for mail delivery. The USPS makes periodic changes to ZIP Codes to support more efficient mail delivery.

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.

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 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. ZIP Code Tabulation 
Areas (ZCTAs) are approximate area representations of U.S. 
Postal Service (USPS) ZIP Code service areas that the 
Census Bureau creates to present statistical data from 
Census 2000. The Census Bureau creates ZCTAs for the United 
States, Puerto Rico, American Samoa, Guam, the Commonwealth 
of the Northern Mariana Islands, and the U.S. Virgin Islands 
for the 2010 Census. Data users should not use ZCTAs to 
identify the official USPS ZIP Code for mail delivery. The 
USPS makes periodic changes to ZIP Codes to support more 
efficient mail delivery. For the 2010 Census, ZCTAs should 
more accurately represent the actual ZIP Codes at the time of 
their delineation than they did for Census 2000. This is 
because that before the tabulation blocks, which the ZCTAs 
are built from, were delineated for the 2010 Census, the 
Census Bureau undertook the process of inserting lines that 
could be used as 2010 Census tabulation block boundaries, 
and these lines split polygons where the result would be that 
a significant number of addresses would occur on either one 
or both sides of the line associated with a single ZIP Code. 
Each 2010 Census tabulation block that contains addresses is 
assigned to a single ZCTA, usually to the ZCTA that reflects 
the most frequently occurring ZIP Code for the addresses within 
that tabulation block. As a result, ZIP Codes associated with 
address ranges found in the Address Ranges relationship file 
may not always match the ZCTA. Blocks that do not contain 
addresses but are completely surrounded by a single ZCTA 
(enclaves) are assigned to the surrounding ZCTA. A ZCTA may 
not exist for every USPS ZIP Code. Some ZIP Codes may not have 
a matching ZCTA because too few addresses were associated with 
the specific ZIP Code or the ZIP Code was not the most frequently 
occurring ZIP Code within any of the blocks were it exists. The 
Census Bureau uses the addresses stored within MTDB to delineate 
ZCTAs, and at the time of the 2010 Census the MTDB primarily 
included addresses for residential or at least potentially 
residential structures, so ZCTAs representing only non-residential 
structures are infrequent. Also, in each tabulation block, if a 
choice existed between using a potential city-style mail delivery 
ZIP Code for an address or a post office box ZIP Code, the city-style 
mail delivery ZIP Code was preferred for the 2010 Census ZCTA 
delineation. The Census Bureau identifies 5-digit ZCTAs using a 
five-character numeric code that represents the most frequently 
occurring USPS ZIP Code within that ZCTA, and this code may 
contain leading zeros.

The boundary information in the TIGER/Line Shapefiles are

their depiction and designation for statistical purposes does 
not constitute a determination of jurisdictional authority

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'.
The University of Florida GeoPlan Center makes no warranties, guaranties

provided by the data sources. The University of Florida GeoPlan Center

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.
