Attribute_Accuracy_Explanation:
This is a polygon shapefile of the Land Resource Regions and Major Land Resource Areas of the conterminous United States. Land resource regions are geographic areas that are characterized by a particular pattern of soils, climate, water resources and land uses. (USDA, Soil Conservation Service, 1981). Major land resource areas are subregions of the land resource regions and comprise smaller homogeneous areas. The scale of this shapefile is 1:2,000,000. The primary use of this shapefile is for regional and national display rather than specific local data analysis due to the small scale (1:2,000,000) of this shapefile.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
MLRA boundaries were revised in the mid-1990s from earlier versions established in the 1970s and 1980s by the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS), formerly the Soil Conservation Service (SCS). The revised MLRA boundary coverage was digitized at the Soil Survey Center in Lincoln, Nebraska, the most recent version of which was completed in January of 1997. Buffer polygons were added to the U.S. national boundaries and shoreline by NRCS National Cartography and Geospatial Center in Fort Worth, Texas, for use with NRCS National Resources Inventory (NRI) digitized sample sites. These buffered boundaries were later removed by the NRCS National Headquarters office, Resource Assessment Division (RAD) in May 2000, and the national shoreline and outer boundaries were made to conform to standard boundaries established for State of the Land series maps (http://www.nhq.nrcs.usda.gov/land). Those standard U.S. national boundaries and shoreline are based on 1:2,000,000 scale 8-digit hydrologic unit coverage obtained from the U.S. Geological Survey, circa 1990, and were edited by the National Center for Resource Innovations (NCRI) in Washington, DC, and subsequently by NRCS/NHQ/RAD.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
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 multicounty 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

Process_Description:
Data was downloaded by GeoPlan in shapefile format from the USDA/NRCS ftp site. (ftp.nhq.nrcs.usda.gov/pub/outgoing/land/arc_export/us48mlra.e00.zip). The shapefile was then clipped to the State of Florida, projected to FGDL Albers HPGN, DESCRIPT item was added based on MLRA, all character items were upcased, internal coverage items were removed, and Area and Perimeter were updated. When received, data was in the following projection: Albers, Datum: NAD 27, Spheroid: Clarke 1866, Units: Meters.

Process_Description:
GeoPlan, during the QA/QC process included the following aspects: 1.) Projected data to FGDL Albers HPGN (See "Map Projection Parameters" below). 2.) Clipped to the State of Florida 3.) DESCRIPT item added based on MLRA 4.) Upcased all character records. 5.) Dropped internal coverage items: Mlra_cov_, Mlra_cov_i 6.) Updated Area and Perimeter
