FLORIDA GEOGRAPHIC DATA LIBRARY DOCUMENTATION

TITLE: FLORIDA HOUSE VOTING DISTRICTS - 2016 

Geodataset Name:       HDIST_2016
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Polygon
Feature Count:         120
GENERAL DESCRIPTION:
This dataset represents the state of Florida House district boundaries.The 2015 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. SLDL stands for State Legislative District Lower Chamber. State Legislative Districts (SLDs) are the areas from which members are elected to state legislatures. The SLDs embody the upper (senate) and lower (house) chambers of the state legislature. A unique three-character census code, identified by state participants, is assigned to each SLD within a state.The boundaries of the 2014 state legislative districts were provided by state-level participants through the RDP and reflect the districts used to elect members in or prior to the November 2014 election.

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.

























These files were specifically created to support small-scale thematic mapping.  
To improve the appearance of shapes at small scales, areas are represented 
with fewer vertices than detailed TIGER/Line Shapefiles.  Cartographic boundary 
files take up less disk space than their ungeneralized counterparts.  Cartographic 
boundary files take less time to render on screen than TIGER/Line Shapefiles.  
You can join this file with table data downloaded from American FactFinder by 
using the AFFGEOID field in the cartographic boundary file.  If detailed boundaries 
are required, please use the TIGER/Line Shapefiles instead of the generalized 
cartographic boundary files.















This data is provided 'as is' and its horizontal positional accuracy
has not been verified by GeoPlan















This data is provided 'as is' and its vertical positional accuracy
has not been verified by GeoPlan















The intended display scale for this file is 1:500,000.  This file should not be 
displayed at scales larger than 1:500,000.














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
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center
makes no representations or warranties about the quality or suitability
of the materials, either expressly or implied, including but not limited
to any implied warranties of merchantability, fitness for a particular
purpose, or non-infringement. The University of Florida GeoPlan Center
shall not be liable for any damages suffered as a result of using,
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: 








In August 2016 GeoPlan downloaded the data from the U.S. Census Bureau at:
https://www.census.gov/geo/maps-data/data/cbf/cbf_sld.html
The data was in the following geographical coordinate 
system: GCS_North_American_1983.  During the QA/QC process GeoPlan 
performed the following tasks.


-Projected the data to Albers Conical Equal Area [Florida Geographic Data  Library]
-Selected features where STATEFP = 12 to select out all Florida features and
 exported to a new shapefile.
-Added state of Florida House representatives and party affiliation for those holding
 office for the current 2016 session.
-Removed unpopulated fields.
-Uppercased all fields.
-Added DESCRIPT field based on the concatenation of "HOUSE DISTRICT" &  attribute DISTRICT.
-Added FGDLAQDATE field based on the date GeoPlan received the data from the  source.
-Renamed the dataset from cb_2015_12_sldl_500k to hdist_2016
Process Date: 201608
