USER NOTES:
All node-link and polygon topological relationships were created and verified using 
ARC/INFO, a Geographic Information System.  The unique identifiers were verified 
using ARC/INFO.  The data was then converted to a shapefile format.
This data set is composed of the 25 Districts having voting representation.
GeoPlan relied on the integrity of the attribute information within
the original data.

The data provide users with information about the locations of congressional districts, 
primarily for planning applications.

The Congressional District data set was created from TIGER/Line data having a nominal 
scale of 1:100,000.

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

THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED
AS LEGALLY BINDING. 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:
Individual files for the Congressional Districts in Alaska, Hawaii, Puerto Rico, 
and the 48 contiguous states were merged into a single data set using 
ARC/INFO.  After completing topological and attribute verification using 
ARC/INFO, the data was converted into shapefile format.
Process Date: 2005

Downloaded the shapefile from BOC. Downloaded congressional district information from USGS (http://www-atlas.usgs.gov/mld/cgd109p.html ) and joined the spatial with the latest attribute data on distritic reprsentatives. Used ArcGIS for topological and attribute verification. Process Date: 2005
Downloaded the shapefile from BOC. Downloaded congressional district information from USGS (http://www-atlas.usgs.gov/mld/cgd109p.html ) and joined the spatial with the latest attribute data on district representatives. Used ArcGIS for topological and attribute verification. 110th Congressional District Boundaries did not change from the 109th. Process Date: 2007
In July 2007 Geoplan obtained the data from the Bureau of Transportation Statistics in CDROM format -GeoPlan extracted this data in shapefile format and removed districts outside of Florida. -The shapefile was reprojected from WGS_1984 Decimal Degrees to the FGDL Albers HPGN map projection. (See "Map Projection Parameters" below). - All records were upcased. - Changed original layer name from cd110 to USDIST_2007. - A DESCRIPT field was added based on the DISTRICTfield - A FGDLAQDATE field was added based on date of data processing Process Date: 20070712
Data imported to ArcSDE and exported as a shapefile. Process Date: 20071218
