TITLE: AGRICULTURAL CROPPING PRACTICES IN FLORIDA
Geodataset Name: CPRAC Geodataset Type: SHAPE Geodataset Feature: POLYGON
GENERAL DESCRIPTION:
This coverage contains estimates of agricultural cropping-practices in counties in the conterminous United States (the coextensive 48 states) as reported in the 1987 Census of Agriculture (U.S. Department of Commerce, 1989a). Agricultural cropping-practice data are reported as either acres, or as a percentage of county area. Agricultural cropping-practice estimates were generated from surveys of all farms where $1,000 or more of agricultural products were sold, or normally would have been sold, during the census year.

USER NOTES:
Most of the attributes summarized represent 1987 data, but some information for the 1982 Census of Agriculture also was included. The polygons representing county boundaries in the conterminous United States, as well as lakes, estuaries, and other nonland-area features were derived from the Digital Line Graph (DLG) files representing the 1:2,000,000-scale map in the National Atlas of the United States (1970). Keywords crops Agricultural cropping-practices Census of Agriculture Counties United States The agricultural cropping-practice estimates in this coverage are intend for use in estimating regional cropping-practices, and in producing visual displays and mapping relative amounts of agricultural crops across broad regions of the United States. A 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:
In 2001, GeoPlan downloaded this data as a southeast regional data set from the Georgia GIS Data Clearinghouse (http://www.gis.state.ga.us/Clearinghouse/clearinghouse.html). The data was then clipped and projected to FGDL Albers HPGN (See "Map Projection Parameters" below).
