Description  
    Abstract
    County boundaries for the conterminous United States.
     
     
    Purpose
    This coverage is intended as a basemap for national level analysis.
     
     
Supplemental_Information
    Procedures_Used
    This coverage contains the county boundaries for the
    conterminous United States.  The coverage was extracted from
    the HUCCO coverage created by Iowa State University for the National Resources I
    Documentation on the HUCCO coverage is available in PDF form
    at http://www.statlab.iastate.edu/survey/nri/papers/geostatistical.pdf
    The county information in that coverage is derived from U.S. Census
    Bureau TIGER files.  ISU made changes to several of the FIPS
    attributes.  Those changes are documented in a PDF files at
    http://www.nrcs.usda.gov/technical/NRI/maps/aboutmaps/fipschanges.html .
    NRCS clipped the coverage to a shoreline created by the National
    Center for Resource Innovations (NCRI).  NCRI derived the
    shoreline from 1:2,000,000 scale USGS Digital Line Graph (DLG) files.
     
     
    Revisions
    This coverage was last updated in 2002.
     
     
    Reviews_Applied_to_Data
    This coverage has received no formal review.
     
     
    Related_Spatial_and_Tabular_Data_Sets
    Other NRI Map Room basemap coverages include hydrologic units and Federal l
    derived from USGS coverages, and a Major Land Resource Areas (MLRA) coverage
    derived from the MLRA map in Agricultural Handbook 296.  These are intended to
    have the same shoreline and outer boundaries, although this has not been
    thoroughly verified.
