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: http://geoplan.ufl.edu/education.html |

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 |
