USER NOTES:
A Each county and statistically equivalent entity is assigned a three-digit Federal Information Processing Standards code that is unique within state. These codes are assigned in alphabetical order of county or county equivalent within state, except for the independent cities, which are assigned codes higher than and following the listing of counties. note concerning data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modelling 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. 1:250000 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 analyses. 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 web pages at: http://www.geoplan.ufl.edu/education.html

DATA LINEAGE SUMMARY:
Data was originally released by US Census Bureau in 2000. Data was downloaded by GeoPlan in shapefile format from ESRI (http://www.esri.com/data/download/census2000_tigerline/index.html). When received, data was in Geographic projection, Datum: NAD83, Spheroid: GRS1980, Units: Decimal degrees. The data was then projected to FGDL Albers HPGN (See "Map Projection Parameters" below).
